Abap Plataform ( BTP ) - On-prem extensions

[Rodrigo_Petrone]

With the idea to decouple the customization from the core. Will we have any changes on the BADI / User-exits / Enhancements definitions from the S/4 on-prem side?

[FrankJentsch]

There are no required changes on the BADI / User-exits / Enhancements definitions from the S/4 on-prem side. The implementation of a BADI remains an "on-stack" enhancement within the same system. There are other types of extension scenarios where a side-by-side approach with SAP BTP ABAP Environment is a recommended approach. Please refer to these TechEd 2021 sessions:

ABAP Strategy - different extensibility options (DEV210)

Hi Rodrigo!

If your transactional operations will still take place on the on-premise system, most likely your exits, enhancements, and BADI's will be called once you trigger that process through an ODATA service or a BAPI/RFC call.

You can run some tests directly from the source system executing the remote function module or the OData service you want to integrate with the ABAP BTP environment in order to make sure everything will work as expected 🙂
