How To Fix TR_AUSL651 - BAPI structure not allowed in foreign package/development class

SAP Error Message - Details

• Message type: E = Error

• Message class: TR_AUSL - Software Delivery Composer Messages

• Message number: 651

• Message text: BAPI structure not allowed in foreign package/development class

What causes this issue?

The BAPI structure does not belong to a package/development class in the
delivery component. BAPI structures are defined interfaces and cannot be
changed or added to.
A BAPI is a fixed structure. Adding fields in between existing fields is
an incompatible change. A field with a certain name must always have the
same position.
Therefore, don't add fields to a BAPI of another component. For example,
an add-on must not add a field to a BAPI of SAP_APPL. If SAP_APPL would
then add a field to its own BAPI then the field of the add-on would
change the position. This is not allowed.

System Response

  The SAP error message TR_AUSL651 indicates that a BAPI (Business Application Programming Interface) structure is not allowed in a foreign package or development class. This typically occurs when you are trying to create or modify a BAPI structure in a package that is not designated for that purpose, or when the package does not have the necessary authorizations or settings.
