In summer 2025 SAP announced its new clean core approach for ABAP development based on Levels (A-D). Most of the BAPIs coming from the ECC era are classified as Level B / classic API.
In many cases they could be replaced by the corresponding ABAP RAP BOs and accessed via ABAP EML or CDS Select statements.
While in SAP Public Cloud systems their usage is obligatory because it is possible to access Level A/ released objects only the question is how to deal with BAPIs in Private Cloud/ On Premise systems. The BAPIs will stay operational in these systems but for new developments as well as for enhancements which try to use functionality beyond the old BAPI scope it will make sense to move on to RAP BOs as well.
