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

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).

      Hello Denys, Indeed, a very nice blog and videos. Thanks!

      Just a heads up. I happened to have published on the same topic very recently as well.

      In a nutshell the blog OAuth2SAMLBearerAssertion Flow with the SAP BTP Destination Service. S/4HANA Cloud. takes much less opinionated approach into the App2App integration with S4HC from anywhere (=Other) with the focus on user identity propagation via a user's identity OIDC mechanism (whether implemented with BTP's XSUAA service as IODC provider or not).

      This can become be very useful in cases the client application is loosely coupled with SAP BTP at all. Like a mobile application for instance.

      I still emphasise on BTP Destination service (the unsung hero so-to-speak) capabilities and qualities especially through the prism of its own REST API capabilities...

      kind regards

      Piotr

      Thanks, Denys.  I have been trying to do a deep create of Business Partner along with its child Customer, following Other Example Requests - SAP Help Portal.   Unfortunately, it raises an exception when I try to execute the create_data_descripton_node( )->set_properties and I can't find any error message in the exception:

      Hi Steve,

      Don't see what's wrong 1-2-3- but no doubt someone on the community might.

      Would you mind posting your comment as question? <copy><paste>

      Thanks, Denys.  I did post it in the community with the tag you suggested a day or so ago but so far no answers.  I did find in the debugger that there is code specifically checking for ‘local’ and deliberately raising an exception in that case.  (I am using the local OData Client Proxy.). So, I wonder if instead of trying to use a deep create, I can insert the Business Partner parent in a first call, and then insert its Customer child entity in a second call.  (I put that in the community as well.). Another alternative would be to use straight https without the OData Client Proxy, but I don’t know if that would work.

      How do we connection BTP ABAP environment with SAP Cloud Integration (SAP CPI) ?

       

      Thank you.

      Hello Denys,

      It’s a nice blog and I was able to post and read data from S/4HANA Cloud from the http service through a browser. However in Realtime I would like to call this service through SAP Cloud Integration.

      Can you please advise or guide me on how to connect SAP BTP ABAP environment http service with SAP Cloud Integration so that we can use it in the iFlow.

      With Kind Regards
      Guru
