Hi,
The field FEBEP-ZUONR 'Assignment number'
gets filled with KUKEY + ESNUM + WAERS (note 417044).
To get the different value filled in the field ZUONR, please, check
the following note (10th point) and make use of the user exit "FEB00004"
Exit FEB00004 is called at the import of SWIFT MT940 in program
RFEKA400:
note 494777 Customer enhancements in electronic bank statement
If FEBEP-SGTXT is empty, BSEG-SGTXT is filled with the data from
FEBEP-CHECT. The remaining space is filled with the first chars from
the note to payee.
Hope this was at least helpful for you.
Regards,
Cristiano
