BAPI_SAG_CHANGE is not updating the field J_1BMATORG
I want to update the Brazilian NCM Code J_1BNBM and Origin of the material J_1BMATORG in the EKPO table. I am using BAPI_SAG_CHANGE and passing the value Item number (EBELP) ,Material Number (MATNR), bras_nbm (NCM Code) and Mat_origin(origin of material) to PO_ITEM and PO_ITEMX . Once executed the BAPI it is returning the message 'Change J_1BMATORG could not be effected' . So it was not updating the field J_1BMATORG, but it is updating field J_1BNBM in EKPO table .
Kindly let me know how to fix this issue.
