Hi Manoj,
BAdI RSU5_SAPI_BADI can only replace Enhancement RSAP0001. Although they are using different technology, they are equal to each other in terms of functionality and purpose: DataSource enhancement during SAPI extraction.
This is not the case for Enhancement MCS10001. It is called at a different moment in time, i.e. during saving SD transaction data. It is normally implemented and maintained by ECC SD consultants.
Best regards,
Sander
