I Customize CS01/CS02 with PCSD0002 PCSD0003 user exit and add some field at Header level and Item level.
But we have current SAP ABAP Z development for Create and Change BOM with standard BAPI as per following ,
BAPI for Create :- CAD_CREATE_BOM_WITH_SUB_ITEMS
BAPI for Change :- CSAP_MAT_BOM_MAINTAIN
Problem : Now How can I save my ZFIELD with using my current program.
