Can we call on-premise CDS view in Cloud ABAP system

[NagaPrakashT]

Hi Experts,

As i know, only HTTP(OData) and RFC(BAPI/RFC Functional Modules) can be called from S/4 HANA On-premise in ABAP Cloud system. Would like to know if we can consume any other artifacts CDS Views, non-RFC enabled FM?

Thanks,

Naga

Hi Naga,

You can create OData services exposing your CDS views on OP. We can't directly use CDS views in SCP ABAP. HTTP(S) and RFC are only 2 means of interaction between OP system and SCP ABAP system.

Hi Gaurav,

Thanks for the clarification. CAP on SAP Cloud SDK also supports both HTTP and RFC to OP systems.

Trying to find a use-case where CAP does not support and is the only way to got ABAP in Cloud(RAP). Any insights on this really appreciate.

Thanks,

Naga

Thanks Naga. Can you share the link mentioning CAP supports RFC to OP systems? I wasn't aware of this.

Hi Gaurav,

CAP does not directly support calling RFC. But if you're using CAP Java you can use: Call a BAPI/RFC Module with SAP Cloud SDK for Java. It seems that the SAP Cloud SDK for JavaScript does not support RFC. But there is a node-rfc npm package. But then the next question arises if that package supports using the destination service in Cloud Foundry.

I think if you want a supported solution for RFC you have to use Java or ABAP.
