bseg-FDGRP empty after RFFUEB00

Hello,

After execution of RFFUEB00, some entries of bseg have changed. Now, its field FDGRP is empty (only 5 entries). Same entries had a value before the execution of RFFUEB00 program.

Is it possible to modify FDGRP field of BSEG table manually? or How can I fix it?

When the user executes a post incomming payment (tx. f-28) with these documents, the Exception condition "E_FDGRP_MISSING" is raised.

Thanks in advance,

Ricard.
