Next event – March 9th 2018 in Frankfurt (right before #sitFRA (registration link)
What can I do at an SAP CodeJam event about SAP Gateway / New ABAP programming model and OData ?
In SAP CodeJam event about SAP Gateway and OData you can try out different ways how to develop OData services depending on the SAP NetWeaver release your backend system and SAP Gateway Hub / SAP Fiori frontend server is running on.
For a detailed overview about the OData development options have a look at my following blog:
OData service development options
For this and all other things you might want to try out we will provide a sandbox system with a fully activated SAP S/4 HANA 1709 appliance which is accesible via the internet.
It is also possible to use your own SAP AS ABAP 751 SP02 Developer Edition which is available as a download. For more details see the blog SAP AS ABAP 751 SP02 Developer Edition to Download.
As a jump start we will provide scripts that describe both recommended development options in detail:
- the new ABAP programming model using CDS views and BOPF objects
- the referenced data source approach using CDS views and classic APIs
To get a first impression you can check out the following blogs that I published about these topics in SCN.
Referenced data source appproach:
CDS view based development as of SAP NetWeaver 750
Customers that have developed CDS Views can either use the Service Builder using Referenced Data Source approach to add for example ABAP code to perform updates via classic API’s such as BAPI’s
Mapped data source approache:
CDS view based development as of SAP NetWeaver 740
If you are using SAP NetWeaver 740 you can leverage CDS views as a datasource for OData services if you are using service implementation using CDS views as mapped datasources.
In contrast to using Referenced Data Sources the main restriction is that annotations are not supported out of the box. You would have to implement them via code based implementation instead.
CDS view based development with SAP S/4 HANA
If you are using SAP S/4 HANA then CDS views are the recommended programming model.
Based on the SAP Online Help I created the following click thru guide
that will allow several participants to perform the sample code in one system.
The read only case is described in the SAP Online Help as well:
What do I have to prepare in advance?
*Remember this is a “bring your own laptop” event**
You have to bring your own laptop with you. On this you have to have installed SAPGUI to work with the SAP Gateway design time, the SAP Gateway Service Builder. In addition you need a browser to access the SAP Web IDE.
We will provide a SAP S/4 HANA Sandbox system for the time of the event. This will however be dismantled afterwards. So if you want to work in a system that is available after the event we recommend that you download the latest SAP AS ABAP Developer Edition. For more details see the blog SAP AS ABAP 751 SP02 Developer Edition to Download.
If you just want to play around with OData services you can register for the SAP Gateway demo system ES5 here. This system however does NOT offer you the option to develop your own code.
In order to connect to the Gateway System and to develop your own services you have to have SAPGUI installed on your desktop. Mac users have to install the Java Gui.
SAP Web IDE
In order to generate a SAP UI5 application that can consume the OData service that you are going to build we will use SAP Web IDE.
There is no need to install anything on your laptop since SAP Web IDE runs in the SAP HANA Cloud platform.
The only thing that you have to do is to register for a free HCP developer account using your SCN credentials.
This you can do here: SAP HANA Cloud Cockpit
You can create a textfile to import the destination of the ABAP demo system. The content of this file is shown in the following box: You only have to replace the IP-Address x.x.x.x that we will share with you when you attend the event.

Get the ABAP Development Tools for Eclipse
Install the latest version of the ABAP Development Tools for SAP NetWeaver. This tool is needed if you want to create your own CDS view but it is also a very convenient tool for development using ABAP. In the following blog I have described how the SAPGUI based SAP Gateway development tool the Service Builder can be used together with ABAP in Eclipse Using SEGW and ABAP in Eclipse .
