My process to implement this ISU_S_PROFHEAD_CHANGE function as a BAPI has been
1.
2.
3.
4. after hitting yes, the create process short dumps.
So I obviously shouldn't have been using it in the 1st place. but whats life without a little challenge.
at this point I had cloned the SAP PROFHEAD Migration object & updated as follows.
the problem I have discovered is in the generated code.
There is no "Move-Corresponding" for the header data.
At this point I go back to the automation structure maintenance, & un-check the Customer structure field.
After saving & attempting to regenerate the migration object...
"PROFILE" is not a structure or internal table with header line.
So still not functional
