I am trying to update the header data field SUPPL_3 of a shipment using BAPI "BAPI_SHIPMENT_CHANGE" .
I am providing the new value for the field in the header and the relevant action for that field .
This BAPI is followed with the "BAPI_TRANSACTION_COMMIT" , still this field doesn't get updated .
And I dont even get any error message while executing this BAPI .
Kindly help me with the solution or idea about what could be the problem .
