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)

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
