Hi Stephen,
I did not find anything standard that you could reach this requirement.
Review the documentation for program RFFOUS_T via trans SE38;
click on Documentation -> Display. The last section provides info on
user exits which can be used to change program output for specific
bank requirements. Specifically, EXIT_100 provides an interface
to change fields in the file header record. Transaction CMOD provides
additional info on the user exit. Also to edit data for record type 5,
batch header record please see EXIT_101.
This is standard behaviour. Check the following exits to modify the
values:
EXIT_RFFOEXIT_100 - Modification of file header records (DTAMUSFH)
EXIT_RFFOEXIT_101 - Modification of batch header records (DTAMUSBH)
EXIT_RFFOEXIT_102 - Modification of CCD detail records (DTAMUSCCD)
EXIT_RFFOEXIT_103 - Modification of CTX detail records (DTAMUSCTX)
EXIT_RFFOEXIT_104 - Modification of addenda records (DTAUMSADD)
EXIT_RFFOEXIT_105 - Modification of batch control records (DTAMUSBC)
If you need to perform any adjustment SAP recommends the usage of PMW
(note 395679).
Hope this is helpful for you.
Regards,
Cristiano
