UPDATE RESB TABLE IN TRANSACTIONS MB21, MB22, IW21, IW22, IW31, IW32

I Need to update a field of RESB table in transactions IW21, IW22, IW31, IW32 if this field is initial.

Could you tell me some badi, exit, or enhancement that I can update the data in the RESB table?

I'm trying to use EXIT_SAPLCOIH_009, and EXIT_SAPLCOIH_005 EXIT_SAPLCOIH_012.
