Hands-On Video Tutorials


What You Will Learn


In the video we cover how to prepare the SAP S/4HANA Cloud tenant to accept connections from the SAP Business Technology Platform (BTP) ABAP environment using OAuth, how to configure a destination in your BTP subaccount pointing to SAP S/4HANA Cloud, and what objects you need to create and code to write to make the API calls.

Ingredients


To follow along, you'll need

  • SAP S/4HANA Cloud tenant with an account privileged to create a communication arrangement (SAP_CORE_BC_COM)

  • SAP BTP ABAP Environment with an account authorized to create destinations

  • ABAP Development Tools (ADT)


Code Sample


For the code sample used in this tutorial and a step-by-step description of the ABAP development activities, visit the SAP Development Center


Integrating the ABAP Environment with SAP S/4HANA Cloud


In this short video tutorial, we cover the concepts, configure the communication arrangement, the destination, and showcase the code sample.

Scenario


Administration Activities


For this scenario, we need to create a communication arrangement with communication system and user on our SAP S/4HANA tenant. For the OAuth 2.0 trust, we need to update a signing key that we can download from our SAP BTP subaccount.

The illustration below shows the administration activities. Previously, it was required to create a service instance of the destination service, create a service key for this instance, and create a communication arrangement in the ABAP environment. This is no longer required and a destination defined at the subaccount suffices (not shown here).


To call the API, as developer, we need to create a service definition using the metadata from the SAP S/4HANA Cloud tenant (or the SAP API Business Hub, alternatively) and an HTTP Service with API handler.


The figure below shows the configuration of the OAUTH2SAMLBearerAssertion destination. Time of writing, the configuration requires the copy and paste of a number of settings from the communication arrangement of the SAP S/4HANA Cloud tenant, as documented


The figure below shows the generated service consumption model from the EDMX. The model is references in the HTTP service object.


The figure below shows the HTTP Service with the handler class (for the sample code see the tutorial) and URL.


The user calling the URL needs to the master data specialist business partner data role (BR_BUPA_MASTER_SPECIALIST).

Over the years, for the SAP HANA Academy, SAP’s Partner Innovation Lab, and à titre personnel, I have written a little over 300 posts here for the SAP Community. Some articles only reached a few readers. Others attracted quite a few more.

For your reading pleasure and convenience, here is a curated list of posts which somehow managed to pass the 10k-view mile stone and, as sign of current interest, still tickle the counters each month.
