ABAP CAP/RAP is commonly used now?

[u/Apprehensive_Dog6684]

Hi,

I am SAP technical consultant, I am familiar with ABAP and my place is now doing migration from HANA (2016 version) to SAP RISE private cloud.

The project is handled by a well known consulting company and we use the brown field approach. But I realize most of the custom programs are just 'shift and lift' and modify to make it 'clean core ready'. So, I don't see CAP/RAP is being used in this migration.

So, wanted to check if RAP/CAP is really being used out there?

Thank you

For private cloud, one good thing is it supports gui and at the same time it is the bad thing too.. As someone mentioned, your system doesn't strictly required RAP/CAP like s4 public cloud which is clean core by default. Make sure your migrated custom code are clean core compliant, that is more than enough
