User Exit - EXIT_SAPMF02D_001

Hi All,

I'm currently using this User Exit EXIT_SAPMF02D_001 to do a check for change in Bank details during 'SAVE' from transaction code FD02.

If there is a change (comparing the import tables with a SELECT statement to the database table), I would need to update the import table parameter T_KNBK-BKONT with a special value.

However, my problem is that the value is only updated within the User Exit. Once it returns to the main calling program (SAPMF02D), the updated value is lost. I've checked the codes and concluded that this User Exit only allows checking of data but not changing them. SAP creates a copy of the table before calling the User Exit function module and passed the copy into the Function Module instead.

Can anyone here suggest an alternative for me? I need to change the data during 'SAVE'.
