I am Using BAPI_PO_CREATE to create PO from Basic IDOC type PORDCR04.
One of the Segments of this IDOC type has been extended with 'Z' segment containing two fields 'Unit of Net weight' and 'Total Net weight'. I want to pass the value of these fields in the BAPI and want to update the fields GEWEI and NTGEW in table EKPO and it should be displayed in the PO (ME23N) as well .
I tried finding some fields in BAPI_PO_CREATE (via Se37) but there is no field available for these. How this is possible (pass the value to BAPI and update in DB tables) ?
