The ABAP CDS views are present already in the S/4HANA on-premise waiting to be used up. The question is how to expose these CDS views from S/4HANA and consume as APIs in SAP BTP.

CDS Views for Sales

In this blog post I will try to explain the steps to identify and expose the ABAP CDS views from SAP S/4HANA on-premise, which can be later consumed as APIs in SAP Integration Suite.

Tcode: SDDLAR

In t-code SDDLAR (CDS Analysis and Repair Tools) in backend S/4HANA on-premise system, you can find other ABAP CDS views consuming the current view based on name.

Now we can use this ServiceName by deploying the SAP Cloud Connector in S/4HANA on-premise and mapping this ServiceName as a source of service in the Cloud Connector.
