Compatible enhancements are interface enhancements that change the BAPI without effecting the downward compatibility of the BAPI. Applications that access the BAPI are not affected by compatible enhancements.
Compatible enhancements are:
A new parameter is added to the BAPI SalesOrder.GetList(), which can be used as an additional selection criteria for selecting purchase orders.
An additional input field for the applicant’s educational background is added to the BAPI Applicant.CreateFromData().
The table below lists the compatible changes in the function module. We cannot guarantee that this list is exhaustive.
