Simple Sample: Writing an entry to SAP Netweaver Gateway using JSON


Skill Level: Beginner

Time Needed: 20 minutes


I recently assisted someone on the forums when they were having trouble creating records in their SAP ECC instance while using Gateway. I thought I would share some very simple code showing what it takes to write an entry into a service via JSON from iOS (Objective C). The reason the title of the document is "Simple Sample" - there are no frills. Whenever I develop a new app, I start small, get the basic functionality working, and proof out the process before getting too creative.


*** If you do not have your own gateway server, you might be able to connect this to the SAP Gateway System which can be found here. Create an account and utilize this service *** DISCLAIMER: Untested as the signup form does not work


The small application sample below uses this document as a starting point. It describes setting up CRUD (Create, Read, Update and Delete) operations for the Bank account list in your back-end, based on the Bank BAPI. For our example, we will be using the Read and Create functionality of the service. Our example will use a open source repository called AFNetworking. The download can be found here, is ARC compatible and is very easy to add and reference in your project. I will skip the basics of creating a iOS project and adding the reference to AFNetworking (but for reference I am using a "Single View" app template in XCode).


Read Operation from your iOS App


Reading from a OData service using JSON can be done in as little as 7 lines of code in objective C (When using the AFNetworking classes). Here is my example code which can be used to read from your service. In my case, I am returning a list of Banks. Below is the code and the output.

Create Operation from your iOS App


Creating a new record adds a small requirement, in that a CSRF (Cross Site Request Forgery) Token needs to be added to the POST request header. If you notice above, I have added this "fetch" header to my GET request, thus returning the key we need along with our data. (2 birds, 1 stone). Here is the create request. Pending it is successful, it will return the record which have been added to your back-end system. Below is the code and output.

Here is a link to the GitHub project to avoid you writing all of this out. Once again - download and follow this useful guide from Gateway team to create the Bank service in your Gateway system, download the project from GitHub, update your gateway server name and details and this will be a useful starting point for creating your next enterprise app.


Disclaimer: Keep in mind the code purposely simplifies the code needed. If you feeling more adventurous:


  1. Ensure your gateway server is using HTTPS.
  2. Instead of using a NSString *dataset, use NSDictionary object/Class to the Request using JSONRepresentation
  3. Add your username and password to the header request, Base64 encoding them.
  4. Instead of writing the JSON response out to a UITextView, add some UITextBoxes and parse the values out.


Can anyone spot the field I forgot to post?

Solution Management Team NetWeaver Gateway and Duet Enterprise

Introducing Virtual Fair for SAP NetWeaver Gateway Customers


Since the introduction of SAP NetWeaver Gateway to the market in October 2011, the product had drawn popularity among our customers as well as partners. So far more than 2500 of our customers used the product to implement innovative solutions to improve their business process. At the same time, our partner ecosystem nurtured a community of partners to develop many SAP NetWeaver Gateway content for different line of businesses and industries.



Virtual Fair for SAP NetWeaver Gateway Customers


In order for our customers to better utilize their investment on SAP NetWeaver Gateway, the Product Management of SAP NetWeaver Gateway will host a Virtual Fair for SAP NetWeaver Gateway Customers to achieve that.


This new initiative offers our partners from our ecosystem to showcase their solutions that harness the power of SAP NetWeaver Gateway.


Discover. Connect. Collaborate


The 3 main goals for this event are:


Discover– Our partners can showcase their solutions to customers who already invested on SAP NetWeaver Gateway.


Connect – Partners connect with our customers to understand their business needs.


Collaborate– Partners can generate leads and customers can understand more about the partner solutions that built on SAP NetWeaver Gateway.


We hope this event can provide a meeting ground not only for the partners to generate leads but also our customers to springboard their investment to business reality. 


What’s next?


We are planning to offer the first installment of this Virtual Fair in late Q2 this year. Stay tuned for more information coming up.

Day 1 at SAPPHIRE - Our NetWeaver Gateway and Duet Enterprise Busy Bees!


The busy schedule for our SAPPHIRE onsite team started already last night with the MSFT pre-SAPPHIRE dinner. Thanks to Duet Enterprise - our joint product with MSFT our team was invited to this fun event.

One more fun event today for the onsite team was the ASUG TV Studio interview about "SAP, Microsoft and Duet Enterprise". Our GW and Duet solution management colleagues Himanshu and Ella were interviewed together with Bill Newman (ASUG Volunteer of Newport Consulting). Some highlights of the discussion are:

  • Duet Enterprise is not the old Duet product, do not mix them up
  • For today’s business users user experience is the key
  • SAP and MSFT are better together for join product like Duet Enterprise so companies already invested in both technologies and skillset can leverage their existing software and resources

Feedbacks and Further Supports for SAP NetWeaver Gateway and Duet Enterprise Partners


In early 2013, we had the honor to host a North America partner focus group event in SAP Palo Alto office for SAP NetWeaver Gateway and Duet Enterprise. There are 8 partners from the NA region joining the one-day event. During the event, we shared with our partners product updates and the progress of successful customer adoption of SAP NetWeaver Gateway and Duet Enterprise. We also took this opportunity to capture thoughts and feedbacks on how we could further improve support for our partners on both business development and technical enablement. Some of the feedbacks resonated with the result of partner survey we conducted at the end of 2012.


Below are the top 5 feedbacks that we collected from our partners during the event.

  1. Strengthen marketing support for SAP NetWeaver Gateway and Duet Enterprise on both partner services and solutions.
  2. Increase transparency of SAP NetWeaver Gateway and Duet Enterprise pricing model
  3. Simplify route to market for partner solutions and guide partner navigating SAP sales channel
  4. Continue to educate partner on positioning of SAP NetWeaver Gateway and Duet Enterprise especially when compared to other SAP offerings
  5. Provide delta functional and technical enablement sessions with the new release of SAP NetWeaver Gateway and Duet Enterprise.

As our answers to those feedbacks, we are now putting together actions to further improve support for our partners in the below areas.  


  1. Continue to increase adoption of partner solutions. A Partner-built Solutions Campaign for 2013 was launched in April. Benefits of the campaign include technical enablement, solution certification, and support of partner solutions go-to-market. This year's campaign continues to target existing SAP SIs, VARs as well as independent software vendors (ISVs). If you missed the webinar sessions, you can find them here
  2. Leverage existing offerings for partners from SAP eco system and channel team. For example Mobile Application Partner Program (MAPP) is a SAP partner program which would help listing partner solutions in SAP store based on SAP NetWeaver Gateway or Duet Enterprise. Enablement sessions for SAP NetWeaver Gateway are provided as part of the MAPP.
  3. Continue to execute social media marketing efforts for SAP NetWeaver Gateway and Duet Enterprise products and partner solutions. Follow both the product channels in Facebook, LinkedIn, Twitter, Youtube, and SCN.
  4. Establish Virtual Fair for SAP NetWeaver Gateway and Duet Enterprise Customers. Virtual Fair is a new type of event we are organizing to increase exposure of partner certified solutions and generate more leads for those solutions. The goal of the virtual fair is to create a platform connecting customers and partners by their common interest – SAP NetWeaver Gateway and Duet Enterprise solutions, from a seller (partner) and buyer (customer) perspectives. The first Virtual Fair is planned for the end of Q2 2013. Detail of Virtual Fair can be found here.
  5. Establish a Partner Enablement Kit to provide:
    • Updated value proposition of SAP NetWeaver Gateway and Duet Enterprise based on new releases
    • Updated positioning of SAP NetWeaver Gateway and Duet Enterprise vs. Other SAP technologies
    • Marketing assets for partners – e.g. guidance on how to participate existing SAP marketing events and navigate SAP sales channel such as inside sales
    • Guidance for  partner on SAP NetWeaver Gateway and Duet Enterprise pricing model
    • Guidance on partner-built solutions campaign and its included benefits as technical enablement, solution certification, and support of partner solutions go-to-market
  6. Increase awareness and participation of SAP Partner-led RDS program. SAP Partner-led RDS program is now an open program for qualified partners and solutions. Partner will leverage SAP’s rapid-deployment solution framework, differentiate their solution offerings, and increase customer adoptions of their solutions by making use of the SAP Rapid-deployment solution momentum to drive their sales. Follow the link to find more information on SAP Partner-Led Rapid-Deployment Solutions.


Many of these proposed improvements are now in full steam progressing while I am writing this blog. For example, SAP NetWeaver Gateway pricing is now available in SAP store and will become part of the pricing guidance included in Partner Enablement Kit. To view the SAP NetWeaver Gateway pricing, go to SAP Store and search for SAP NetWeaver Gateway User License. Scheduling of the Virtual Fair is also getting closed to be released. So stay tuned for the coming.

Configuring SSL Connection to SAP Systems in SAP NetWeaver Gateway Productivity Accelerator




Following the release of the SAP NetWeaver Gateway Productivity Accelerator and the blog post by Martin Bachmann, more and more people keep asking me how to configure their Gateway system within the GWPA tool, in HTTPS protocol. So I figured it might be worthwhile to post a short explanation that hopefully clarify what needs to be done in order to add a SAP NW Gateway secured connection.


Follow these 3 steps:
• Export the server certificate (that is the root certificate of the Gateway server)
• Import the server certificate to the list of trusted CAs (Certificate Authorities) in your JRE
• Add the connection in SAP NetWeaver Gateway Productivity Accelerator in Eclipse


Step 1: Exporting the certificatelock2.png

Easiest way I've found to export the certificate is to go to your browser and just export it from there: enter some URL of a service on the SAP NW Gateway system you would like to configure. Click on the lock icon on the address bar and then on View certificates (if using Chrome, after clicking the lock icon go to the Connections tab and then Certificate information). Select the Certification Path tab and click on the root certificate before clicking on View Certificate. Then, go to the Details tab and click on Copy to File…

Follow the wizard (select the Base-64 encoded X.509 (.CER) format, and choose the file system location to export to).




Step 2: Importing the certificate to the CA list

This is a rather simple step, but a bit tricky as you need to make sure you import the certificate into the correct JRE installation in case you have multiple JREs on your machine. To check which JRE installation is used by your Eclipse instance, go to Eclipse Preferences (Java > Installed JREs). I used the Portecle tool which is a user friendly GUI application for creating, managing and examining keystores, keys, certificates, certificate requests, certificate revocation lists and more. You can get it from:http://portecle.sourceforge.net/

Open the Portecle tool and Open the Keystore File of your JRE (cacerts) should be located in <JRE installation path> ..\jre\lib\security.

Enter the password to the keystore: changeit

Then go to Tools > Import Trusted Certificate, and select the exported certificate from where you have saved it. Save and close the tool.


Step 3: Add the connection in SAP NetWeaver Gateway Productivity Accelerator in Eclipse

After installing the Productivity Accelerator, in Eclipse Preferences, add the system connection using HTTPS and SSL port.

Day 3 – More engagements with customers and partners before the closing bell


Time flies, SAPPHIRE reaches its final and 3rd day of the event. Lots of traffic circled around the DT625. Ella, Mustafa and Himanshu made sure they did not miss any customers to explain and pitch on how SAP NetWeaver Gateway can help their businesses.

During the final Micro Forum session, we had customer Dr. Pepper to present with Himanshu. The interactive discussion drew a lot of attendees. The session revealed how businesses can offer people new ways to work by linking them to SAP applications from various user environments using Duet Enterprise and SAP NetWeaver Gateway technology which can benefit your business, IT department, end users, and extended network.

So don't delay and reserve your seat now! Register for our training sessions.




SAP NetWeaver Gateway deployment options in a nutshell



- added pro's and con's to the deployment options



In the past I have been frequently asked which deployment option I would recommend for SAP NetWeaver Gateway. The official documentation can be found here in SAP Online Help.


Root cause for this discussion was that basic Gateway functionalities if running on releases prior to 7.40 are contained in different AddOns that have to be
deployed separately.


While in releases prior to 7.40 the Gateway server or hub functionalities require that the software components GW_CORE and IW_FND are deployed on the server system, the Gateway backend enablement functionalities required that software component IW_BEP had to be deployed.


As of SAP NetWeaver 7.40 and higher you don’t have to decide where to put the Gateway core components since SAP has taken the decision for you .


This is because the component SAP_GWFND is installed as part of the 7.40 standard and includes the functional scope of IW_BEP, GW_CORE, IW_FND and in addition IW_HDB.


SAP NetWeaver Gateway server functionalitiesSAP NetWeaver Gateway backend enablement
and earlier


So instead of discussing where to deploy which AddOn the discussion will be around whether you will go for a hub architecture or whether you will activate the Gateway service on the SAP Business Suite system itself (also called “Embedded Deployment”).


Since the Gateway core components will be part of each system running on top of NetWeaver 7.40 in the future you still have basically three options how to run SAP NetWeaver Gateway services in a system landscape.


In contrast to the description in the online documentation I am differentiating between two types of hub deployment. One where the service deployed in the backend and one where the service is deployed on the hub.


Option 1 (hub architecture)


In this case the Gateway server functionalities are only used on one dedicated server, the hub system. The services are deployed on the backend systems and are registered on the server. The Gateway service is thus deployed in the Gateway backend systems where either IW_BEP is deployed systems or that are running on top of 7.40 leveraging the core component SAP_GWFND.



+ Routing and composition of multiple systems is supported

+ Single point of access to backend systems

+ Hub System can be based on a newer release (7.31 or 7.40)  that supports additional authentication options (Kerberos, SAML Browser protocol)

+ Hub System can be based on a newer release (7.31 or 7.40)  that supports SAPUI5

+ Enhanced security because of no direct access to the backend system

+ Direct local access to metadata (DDIC) and business data, meaning easy reuse of data



- Additional server needed for Gateway


option 1 hub deployment development in the backend.PNG


Option 2 (Hub architecture with development on the server)


In this case the Gateway server functionalities are only used on one dedicated server, the hub system. In contrast to option 1 also the service deployment takes place on the hub system. This option is used if either no development must be performed on the backend system or in case of releases prior to 7.40 if it is not allowed to deploy the AddOn IW_BEP in the backend. In this case the developer is limited to the interfaces that are accessible via RFC in the backend.


Pro's: (in addition to the ones mentioned in option 1):

+ no need to install (and upgrade) Gateway AddOn’s in the backend

+ services developed by partners do not need any deployment on the backend systems


Con's (in addition to the ones mentioned in option 1):

- access is limited to remote enabled interfaces (RFC function modules, BAPI’s, BW Easy Queries, SPI Objects)

- remote enabled interfaces might not be optimal suited (e.g. they might not offer appropriate filter options)

- GENIL objects cannot be accessed remotely

- Additional server needed for Gateway

- NO direct local access to metadata (DDIC) and business data, meaning reuse of data is limited to remote access as mentioned above



option 2 hub deployment development in the server.PNG


Option 3 (Embedded architecture)


In this case the service is deployed on the same system where it is registered.



+ Less runtime overhead as one remote call is reduced



- If multiple SAP Business Suite systems are used Gateway would have to be configured multiple times

- Routing and composition cannot be used

- Upgrade of AddOn’s in a backend system in larger companies is usually only possible once or twice a year

SAP CodeJam about SAP NetWeaver Gateway - Where to go next ?


Setting the scene


Last week I attended the SAP CodeJam event in Eindhoven that was all about SAP NetWeaver Gateway. Nearly 75% percent of people that had registered also showed up so we had a packed room full of developers as you can see on this picture.


First of all I have to thank Ciber Nederland for hosting this event in their location and Craig Cmehil, who created the SAP CodeJam event concept to make this happen. In our session we were able to leverage a cloud based system landscape that consists out of an ERP with a SAP NetWeaver Gateway server deployed on it and a CRM backend that were accessible via the internet. Here my thank you goes to my colleagues that have been busy to create this system landscape.



I started to provide a short introduction to SAP NetWeaver Gateway to the participants (here I had to use Powerpoint because not everybody knew about SAP NetWeaver Gateway) and showed how to develop a service in 5 minutes (actually it took a little bit longer because I had to talk as well ).


After this introduction it was time to code and to ask questions for the participants and to do networking.


Participating partners were encouraged to sign up for our 2013 campaign - SAP NetWeaver Gateway Partner-built Solutions Drive.


What are the lessions learned ?


It worked !


Since we used a cloud based system landscape that was accessible via the internet all participants were able to use it without a problem.


Some How To Guides need to be updated


It turned out that some How-To-Guides that can be found on SCN are unfortunately out of date. This is no wonder since we have developed lots of new features in the last 2 years. We started to set up a Wiki for SAP NetWeaver Gateway - Self pace learning where you will find the most up to date content.

We will do it again !


The SAP NetWeaver Gateway team will support additional SAP CodeJam events about SAP NetWeaver Gateway with speakers from our team if you want to have them.


So if you are interested that a SAP CodeJam event about SAP NetWeaver Gateway will be hosted near you or at your location, please let me know and we can work on hosting a SAP CodeJam event as described in the following document.


Best Regards,


NetWeaver Gateway and Duet Enterprise post SAPPHIRE Orlando Digest


Our SAPPHIRE Orlando onsite team came back pretty exhausted. Between delivering sessions, covering the demo station, meeting customers, attending networking sessions there was nearly no breathing room.

There was a BIG interest for NetWeaver Gateway as well as Duet Enterprise. Our Duet Enterprise round table with Dr. Pepper was simply packed. Our demo pod was a hit too.


A huge interest on Gateway was generated by SAP Fiori which is a collection of apps with a simple and easy to use experience for broadly and frequently used SAP software functions that work seamlessly across devices – desktop, tablet, or smartphone. Those apps are built on NetWeaver Gateway and HTML5.


The first release of SAP Fiori includes 25 apps for the most common business functions, such as workflow approvals, information lookups, and self-service tasks.More details about Fiori are under http://scn.sap.com/docs/DOC-41598

Our solution managers Himanshu and Ella were on ASUG TV session as panelists. Click here to watch the interesting discussion about SAP and Microsoft's partnership.


ASUG TV abstract: Duet Enterprise is the result of SAP and Microsoft's 20-year partnership. Panelists Bill Newman, from Newport Consulting, and SAP's Himanshu Pande and Ella Morgulis look at what is it, how it benefits customers and why customers aren't flocking to it.


We also conducted a series of customer and partner interviews to get their impression working with our Gateway or Duet products. Want to know what they think about the products, definitely check out the videos:

All About System Alias and Routing of Requests in SAP NetWeaver Gateway


Recently I have been answering queries around the system alias configuration in SAP NetWeaver Gateway, I thought I will share information on the same in this blog.



You just have to know the basics of developing OData services using SAP NetWeaver Gateway.

This blog does not cover web service part of the System alias.


System Alias is the wrapper around the RFC_Destination + the information related to routing of requests which is created using transaction code SPRO in Gateway HUB system (IWFND). Here is the navigation path:


SPRO -> SAP Reference IMG -> SAP Netweaver -> Gateway -> OData Channel -> Configuration -> Connection Settings

-> SAP NetWeaver Gateway to SAP System -> Manage SAP System Alias




SAP NetWeaver Gateway System Alias has the following properties:


SAP System Alias: Name


Description: <Enter the description>


Local GW: N/A


Local App: Check box that specifies the deployment of component IWBEP .


RFC Destination: RFC destination you created using the transaction code SM59

Software Version: Default/which ever applicable

SystemID: Not Required

Client: Not Required

WS provider Sytem: Not Required


Deployment Examples and its System alias configurations:



Example 1: Local APP


In this case (Example 1: Local APP), System alias configuration should have Local App flag set as IWFND and IWBEP are together and RFC destination should point to SAP back-end. RFC destination will be used by BEP data provider to call the RFC from SAP Backend.


Now how do you get the RFC destination in your Data provider?


Follow the code below


DATA lo_destination_finder TYPE REF TO /iwbep/if_destin_finder.

DATA lo_dp_facade TYPE REF TO /iwbep/if_mgw_dp_int_facade.

DATA lv_destination TYPE rfcdest.



* Get RFC destination

lo_dp_facade         ?= /iwbep/if_mgw_conv_srv_runtime~get_dp_facade( ).

lo_destination_finder = lo_dp_facade->get_destination_finder( ).

lv_destination        = lo_destination_finder->get_rfc_destination_via_rout( ).





Example 2:Remote APP  


In this case (Example  2: Remote App), System alias configuration should not have Local App flag set, as IWFND and IWBEP are in different SAP systems and RFC destination should point to back-end where IWBEP is present which is used by IWFND to route the calls.

Here IWBEP data provider and metadata provider classes can use the local RFC Function Modules as well.





Example 3: Local App ,all the components in SAP Business Suite/Backend

In this case (Example 3: Local APP), system alias configuration should have Local App flag set as IWFND and IWBEP are together and RFC destination can be empty as all the components are in the SAP back-end.


System Alias in Service Builder:

There is another system alias which is used by Service Builder'sservice maintenance node which is used only in design time for registering and maintaining  the service in the Gateway HUB from IWBEP(Service Builder) system .





System alias in this case should be created/configured in the system where IWBEP is installed i.e using transaction code SPRO. Navigation path below:


SAP Reference IMG -> SAP Netweaver -> Gateway Service Enablement -> Connection Settings to SAP Netweaver Gateway -> SAP NetWeaver Gateway Settings



System Alias here points to the HUB system.


It has the following properties


Destination System: Destination system name


System alias name

RFC Destination



RFC Destination here is used to navigate from IWBEP(Service Builder) system to Gateway HUB System(IWFND) when the Register or Maintain or Error Log Button is clicked in the Service Maintenance node of Service Builder





Once the Maintain button is clicked,control goes to the corresponding IWFND system's /iwfnd/maint_service






And that is all!! Feel free to contact me if you have any queries:)


Thanks and Best Regards,


Making way through Gate, Finding some REST !


I guess you might be puzzled with the title of my blog. Let me help to clear the puzzle. This blog is all about SAP NetWeaver Gateway!

There will be few questions in your mind about this stuff from SAP.


You may have some of below questions in your mind like,

1)   What is SAP NetWeaver Gateway? And what is the importance of it?

2)   How is it different from SAP PI?

3)   What skills are required to learn it?

4)   Learning sources?


This blog is just an attempt to answer above questions from the Research I did so far on this new stuff.

To answer 1st question,

In very simple terms, SAP NW Gateway can be viewed as one of the OData producers.

OData producers are services that expose their data using the OData protocol. You can find other OData producer list at http://www.OData .org/ecosystem

You may ask what OData is then.

Well, OData is Open Data Protocol!

You can refer below definition.

The Open Data Protocol (OData) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications today. OData does this by applying and building upon Web technologies such as HTTP, Atom Publishing Protocol (AtomPub) and JSON to provide access to information from a variety of applications, services, and stores.  OData is being used to expose and access information from a variety of sources including, but not limited to, relational databases, file systems, content management systems and traditional Web sites.

OData protocol is used for creating Representational State Transfer (REST)-based [REST] data services, which enable resources, identified using Uniform Resource Identifiers (URIs) and defined in an abstract data model, to be published and edited by web clients within corporate networks and across the Internet using simple Hypertext Transfer Protocol (HTTP) messages.

[Reference -  http://www.OData .org/ ]

If this technical definition is too much then in simple terms, OData is used for creating REST based data (Web?) services.

And then you will ask, what is REST?

Representational State Transfer (REST) is kind of architecture/protocol something similar to SOAP protocol but with more advantages over SOAP.

A RESTful web service (also called a RESTful web API) is a web service implemented using HTTP and the principles of REST.

The world of web is now divided between REST and SOAP and nowadays most of the applications are using REST.

Refer http://geeknizer.com/rest-vs-soap-using-http-choosing-the-right-webservice-protocol/ to know more on REST vs. SOAP

I hope, by now, you might be familiar with OData, REST terminology and importance of REST over SOAP.

Now coming back to SAP Gateway,

SAP NetWeaver Gateway is a development framework, which is available as an SAP NetWeaver Application Server ABAP (AS ABAP) add-on, which you can install on top of your existing SAP Business Suite or application platform.

SAP NetWeaver Gateway offers development and generation tools to create OData services to a variety of client development tools. Put simply, it establishes a connection between SAP Business Suite data and target clients, platforms, and programming framework.

[Reference -  http://help.sap.com/saphelp_gateway20sp06/helpdata/en/71/376ab03f824ea5bfd0a0e3a307205b/frameset.htm ]

Also note that SAP NetWeaver Gateway only provisions RESTful services.  It cannot be used for consumption of services.

As most of us know that we can create web services on top of RFC which are SOAP based, there was no way to expose SAP data to outside world in the form of RESTful protocol and for that reason, SAP NW GW comes into picture. It simply helps us to expose this data in the form of REST based OData.

This light weight REST based data then can be easily consumed by tablets, mobile devices or web applications.

One question may pop up in your mind is how REST based web services can be light weight compared to SOAP and for that you need to know about JSON !

JSON (JavaScript Object Notation) is a text-based open standard designed for human-readable data interchange. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for many languages.

The JSON format is often used for serializing and transmitting structured data over a network connection. It is used primarily to transmit data between a server and web application, serving as an alternative to XML.

In simple terms, it is an alternative to XML but with few more advantages over XML.

Let’s see the difference between JSON vs. XML at http://www.json.org/xml.html

JSON with REST do have lot more advantages over XML with SOAP. Refer, http://blog.feedly.com/2009/03/03/jsonrest-vs-xmlsoap/

With all this information, it is clear that SAP want to leverage the capability of REST based services to outside world for consumption due to advantages of REST based OData.

Data exposed by GW service, is light weight, can be easily consumed by application and devices. One of the important consumers is SAPUI5 based applications. With SAPUI5, we can easily build web application or mobile application on top of GW service.

I hope this answers the second part of first question.

Back to 2nd question, how is it different from SAP PI?

Refer this link http://scn.sap.com/docs/DOC-25547

Before going through this document, I thought SAP NetWeaver Gateway as some sort of middleware and thought why SAP did not provided this capability with PI.

If we look back into SOAP based web service generation on top of RFC then it make sense to have this kind of facility in ABAP stack to be able to create REST based service on top of RFC and for this very purpose ABAP developer can use his/her all time favorite SE80 for GW Data Model and GW Consumption Model

Gateway tools in SE80.jpg


As ABAP Developer may know more about which BAPI, RFCs, BOL(in CRM) to be used, what fields to be selected for various REST based operation (GET, POST, DELETE and UPDATE – in HTTP verbose), he/she will be best suitable person to develop GW services.

In future, REST based adaptor may be provided with PI but still it makes more sense to have SAP NW GW to develop GW REST based services.

We may not be surprised to see that GW services again consumed in PI for monitoring, governance purpose. This is something similar to have PI for SOAP based web service despite of the fact that SOAP based Web service can be directly consumed without PI by external applications.

This all stuff makes it very clear that both PI and GW have their own purpose!

Now coming back to third question, what skills are required to learn it?

With all above discussion and knowing the fact that SAP NW GW is on ABAP stack, embedded with SE80, ABAP development skills will be the best suited to learn SAP NW GW.

[P. S. - Eclipse based tools can be used for GW modeling etc. With ABAP on eclipse, this will be again simpler for ABAP developers]


Finally, the last and important question, learning sources?


As we are more familiar with RFC, you can first start with How to Guide at http://scn.sap.com/docs/DOC-5010

This shows how one can develop Gateway service on top of RFC.

Some business objects, such as Sales Orders or Purchase Orders, consist of header and line item data. Thus, when creating such business objects, it makes sense to use hierarchical or nested data in the creation request. SAP NetWeaver Gateway can be used to create and expose a service that allows for the creation of these business objects.

In SAP NetWeaver Gateway, the OData  Channel provides deep insert functionality to accommodate the creation of an entity along with its associated entities in one request. The deep insert functionality is provided in ABAP interface /IWBEP/IF_MGW_APPL_SRV_RUNTIME, method CREATE_DEEP_ENTITY.

Refer this link on this scenario, http://scn.sap.com/docs/DOC-22305

Finally you may be interested to develop web application based on GW service and how about using SAPUI5 for User interface which will consume GW OData service!

Refer these step-by-step document on it - http://scn.sap.com/docs/DOC-33792 and http://scn.sap.com/community/developer-center/front-end/blog/2013/05/31/how-to-create-sapui5-application-consuming-gateway-service-with-the-help-of-sap-nw-gateway-plugin


Some of you may get one question whether it is possible to develop REST based services without Gateway? For those, this link will be helpful http://scn.sap.com/community/abap/blog/2013/01/24/developing-a-rest-api-in-abap


We explored lot and tried to open gates of new world based on Open Data. Now be relaxed and take some REST!


Gateway Productivity Accelerator 1.0 Launched


Last September I published my blog introducing Gateway Service Builder which simplifies the development and generation of OData services on top of the SAP NetWeaver ABAP stack and SAP Business Suite. At that time we knew already that having strong developer support for SAP NetWeaver Gateway on on-premise ABAP systems is important but not sufficient. We will also need to do more to cater for OData service development on upcoming platforms like SAP HANA Cloud and Gateway as a Service. Customers will run on-premise systems in hybrid landscapes together with on-demand systems, consuming data from both. Thereforewe will need a set of tools that span across different platforms and provide an easy and efficient development experience around OData. This is why we decided to build Gateway Productivity Accelerator as the next major building block for the development of user-centric applications on SAP.


We have now completed and published Gateway Productivity Accelerator 1.0 (GWPA). GWPA is a set of developer tools in Eclipse which greatly improves the productivity of developers around the consumption and the provisioning of OData:


  • A graphical modeler to paint the entity relationship model and to declaratively define all elements of an OData model, currently along the OData V3 specification. We spent much effort on usability and intuitive handling. For instance, there are several autolayout modes for newly imported models which come without layout information. A miniature view helps navigating in larger models and speed-buttons support fast editing.
  • The modeler offers comprehensive validations for the data model while you are defining or enhancing it.
  • You can import existing data models from a file or from an already running OData service.
  • Of course you also can export data models (currently V2 and V3) for handover to a service implementation, for instance in Gateway Service Builder on ABAP.
  • GWPA 1.0 already supports references to OData vocabularies, a powerful new concept that was introduced with OData V3.
  • GWPA integrates the Gateway Consumption Tools for iOS, Android, HTML5, UI5, Java SE and PHP, which were already published on SAP Service Marketplace and which allow the easy generation of service proxies or even full-blown starter applications for the most common client technologies.




We believe, that GWPA is a significant shipment also beyond its functional capabilities. Let me explain why.


First (and only) OData Modeler in Eclipse

So far the only (setting the Gateway Service Builder on SAP NetWeaver ABAP aside) relevant OData Modeler was part of Microsoft Visual Studio. Non-Microsoft developers were restricted to modeling their OData data models in a plain XML editor. Now any Eclipse developer can freely download and use GWPA to define the OData data model that he needs.


GWPA is platform agnostic

At SAP we now have more than one platform and are serving more and more client technologies. When OData is the agreed standard protocol for user-centric consumption, GWPA can become a commonly used developer tool to model and consume OData services on the most common clients on top of any SAP platform. This will simplify the development process and reduce the TCD for SAP based development.


GWPA is designed to be re-used by other Eclipse tools

This is important if you want to generate code for either service implementations or for client-side code. GWPA uses an OData domain model built on Eclipse Modeling Framework (EMF). From there, other Eclipse tools can extract information of the data model for a number of purposes like data-binding or code generation.


The GWPA OData Modeler becomes Eclipse Project "Ogee"

To drive the overall adoption of OData and the extension of the tool into other technologies SAP has initiated the contribution of the OData modeler under the Project Eclipse "Ogee". There the Eclipse community can extend the tool in many ways together with the committers from SAP.


GWPA shipped jointly with other key Eclipse tools from SAP

At the same time as GWPA, we published several other SAP development tools for Eclipse for ABAP, HANA Cloud and SAPUI5 on the same public update site. Now anybody can download SAP developer tools for Eclipse from one public location and install them in one instance of the two most recent Eclipse releases. And last, but not least, the NetWeaver 2013 End-2-End Developer Scenarios were published on SCN with both GWPA and Gateway Service Builder taking important roles in there. Both publications are important steps towards a more harmonized developer experience for SAP customers and partners.


So, I hope you are curious by now and will try out our new Gateway Productivity Accelerator. GWPA 1.0 can be downloaded from SAP's public Eclipse update site on SAP HANA Cloud. Let us know, what you think of it.

How to create Android Application consuming OData Service with help of Gateway Productivity Accelerator (GWPA)


It was my dream to build at least one android application which will display SAP data on mobile/tablet devices. As I am not very much skilled in developing android application, I was struggling on how to start with this. And then I came across GWPA and started exploring it. I explored it; I liked it and now I'm loving it!

It is very simple to create android application consuming OData with the help of Gateway Productivity Accelerator (GWPA) plug in installed on Eclipse IDE.

Let’s get into the details,

Introduction -

In this technical blog, I will focus on how we can build simple Android application consuming OData service with the help of SAP NetWeaver Gateway Productivity Accelerator (GWPA).

To know more about GWPA, please refer http://scn.sap.com/community/netweaver-gateway/blog/2013/06/03/gateway-productivity-accelerator-10-launched

It can be downloaded from https://tools.hana.ondemand.com/#gateway


Prerequisites –

We need to follow steps as mentioned below [Reference - https://tools.hana.ondemand.com/#gateway ]

Installation Instructions

To start using SAP NetWeaver Gateway Productivity Accelerator (GWPA), proceed as follows:

  1. Download and install Java SE6 .
  2. Download and install the Eclipse IDE for Java EE Developers from Eclipse .
  3. Install the SAP NetWeaver Gateway Productivity Accelerator (GWPA) feature(s).

From the Eclipse menu, choose Help> Install New Software...
Add the URL
Select the feature(s) you want to install and follow the steps of the installation wizard.
For information about the individual features, see the documentation.


To Develop Android application using GWPA, we need to install Android SDK tools on Eclipse IDE and then install GWPA features.

  • Toolkit for Android (GWPA)
    The Android Toolkit consists of an environment, a pattern and templates, suitable for developing SAP solutions for use in the Android environment.
    Prerequisite for installation of this feature is to install the
    Android SDK Tools.

Once you install Android SDK tools, it will look as below under Window --> preferences.


After doing all these steps, I faced issue with android application regarding getting error, “R cannot be resolved to a variable” and hence after searching lot on it, I resolved it by installing Android SDK Build-tools and hence your Android SDK Manager image should look as below.


After this step, you can start installing Toolkit for Android (GWPA) as mentioned below. You need to select checkbox for Toolkit for Android (GWPA).


Once installed successfully, you can open Windows --> Preferences and check under SAP NetWeaver Gateway.


Please note: we do not require separate installation for SAP OData Mobile Client SDK.

With all above required steps, you are now ready to develop Android application!


Procedure -

Create new project. Under OData Development, select Starter Application Project.


Give appropriate project name, select Build Target and package name and press Next.


We can create 3 types of application using below templates. Here, we will select List/Details Application.


Now, we need to select service URL from Remote location. Click on Catalog.


Click on Manage Connection if no connection is maintained earlier.


As displayed below, provide required details and click OK.


P.S. - If you do not have access to SAP NetWeaver Gateway system then you can access demo system from SAP at http://scn.sap.com/docs/DOC-31221?rid=/webcontent/uuid/1051f6d9-e87a-2e10-d188-e2786c7878b1 and accordingly configure connections and access OData services. Please refer my blog http://scn.sap.com/community/developer-center/front-end/blog/2013/05/31/how-to-create-sapui5-application-consuming-gateway-service-with-the-help-of-sap-nw-gateway-plugin and see section Additional Details for more information.

If the connection is made, you will be able to see services. For this demo, we will select service RMTSAMPLEFLIGHT and click OK.


Provide Activity title, select Activity type and add fields.


Add 2nd Activity of type Details.


We selected Flights as List activity and FlightBooking as Details Activity. Our final project structure will look something like below screen.


As displayed below, SAP Gateway system service details will be found under res/raw folder.


Also the auto-generated code provides commented code to handle Sybase Unwired Platform (SUP) server mode. This is really nice feature as when we have SUP, we need not to modify much logic.


Now we are ready with Android application and want to test it. To test android application, you can use Real device or Android Emulator http://developer.android.com/tools/help/emulator.html

We need to manage device using AVD. Please refer http://developer.android.com/tools/devices/index.html

An Android Virtual Device (AVD) is an emulator configuration that lets you model an actual device by defining hardware and software options to be emulated by the Android Emulator.

As displayed below, AVD can be added.


That’s it!!!

Now we are absolutely ready to test our application on emulator. We need to test as mentioned below,


Under Console screen, you will be able to see the log of AVD launch etc...


Please note: Android emulator sometime is very slow and hence you need to be patience and can take break for Coffee.


AVD will launch emulator device as displayed below,


Here sometime you need to press F2 or keyboard commands as per your AVD settings. Refer Keyboard commands at http://developer.android.com/tools/help/emulator.html

You may see screen as below. Here you can see all your Android based application. In this case, you can see MyFlightAndroidApp. Double click on app icon.


It will launch login screen. Provide credentials that you used while connecting to your gateway SAP system.


Under LogCat window, you will see the log of application being executed.


After successful launching, you will see the Flights list view.


Selecting any item will open details screen for FlightBooking as below


You can search for different flight id and it will be displayed accordingly.


Note that under LogCat window, all these events will be logged which can be very useful for troubleshooting purpose.



Closing Remarks –

With the help of SAP NetWeaver Gateway Productivity Accelerator (GWPA), we can create Android application with very minimum efforts.

This step-by-step blog is written to explain how we can,

  1. Install Android SDK tools, GWPA etc. in Eclipse IDE.
  2. Configure SAP NetWeaver Gateway system and search for OData services
  3. Create simple Android application
  4. Configure and Launch Android application on ADV
  5. Use Console and LogCat for troubleshoot purpose



GWPA is extremely helpful tool from SAP to leverage OData capability and it will certainly helpful for all developer community who want to develop simple android application based on SAP business suite data in the form of OData.

It is generating starter application which we can modify as per our business/organizational requirement

How to create Android application based on SAP Workflow with help of Gateway Productivity Accelerator (GWPA)


In my earlier blog, I explained how we can create Android application consuming OData with GWPA. In this blog, I will explain about creating Android application based on SAP Workflow!

Basically we will use demoformabs (Demo Absence Notification workflow) having workflow ID WS70000704.

We will use steps 000087 Create notification of absence and 000048 Approve notification of absence as highlighted below.


And workflow service WFSERVICE shipped with gateway.


You can follow detailed steps mentioned in How-to guide athttp://scn.sap.com/docs/DOC-29199

Now it’s time to develop android application!

Create new project and provide details.


Select Workflow Application.


Assuming you configured the connection for backend SAP NetWeaver Gateway system, you will be able to see all services available. Now search with WF and you will find available workflow services in your system. Select workflow service WFSERVICE.



Click on OK and Finish.


Finally, application structure will look as below.


Now it is time to test our application.


Select Run As --> Android Application. It will launch Android emulator where you will be able to see your application. Provide credentials which you used to configure backend SAP NetWeaver Gateway system.


It will display workflow items available in your work list. Here, I have below 3 tasks in my work list.


Click on any single task which will open details of that task.


On clicking Decision button, it will give 2 options as displayed below.


You can then put comments and process it.


After processing task, it will disappear from your inbox.


You can see workflow items in transaction SBWP (SAP Business Workplace)


If you again process items in Android application, accordingly it will be removed from you inbox. Now I processed one more item and hence my inbox will display single task.


We can verify again by going back to SAP Business Workplace. And as per below screen, it contains single work item.



It is very easy to develop workflow based android application with the help of SAP NetWeaver Gateway Productivity Accelerator (GWPA). we can develop nice android application just within few minutes!


SAP Fiori LL03 - Apply all SAP Notes before implementation


SAP Fiori Lessons Learned 03.

Apply all SAP Notes before implementation.



SAP Notes are listed in the installation guide. http://help.sap.com/fiori

Responsibility is not clear for applying SAP Notes.

Bug fix notes are available in the SAP Service Marketplace.


Lessons Learned:

If you did not apply SAP Notes, you have to spend 2-3 weeks for troubleshooting.

Searching, Checking, Applying SAP Notes may takes full 2 days but it saves your 2-3 weeks troubleshooting time.


1. Define clear responsibility for applying SAP Notes. Is it a job for system admin or application consultants?

2. Double chekc that all SAP Notes listed in the install guide have been applied.

3. Search bug fix notes in the SAP Service Marketplace. http://service.sap.com/notes

     For example:

    Search term: fiori

    Search term: SAPK-60001INSRA004

                            The oData add-on component name for "My Travel Requests" is "SRA004". The naming convention is "SAPK-" + base version "600" + support package "01" + "IN" + technical components "SRA004" => SAPK-60001INSRA004

     Search term: SAPK-10001INUISRA004

                            The UI add-on component name for "My Travel Requests" is "UISRA004". The naming convention is "SAPK-" + base version "100" + support package "01" + "IN" + technical components "UISRA004" => SAPK-10001INUISRA004
