Required to Enhance CAT7 Transaction

Hi All,

I need to enhance the CAT7 Transaction as I need to modify the value of sender Cost Center (SKOSTL) and receiver cost center (RKOSTL).

I got two BADI's : FAGL_DERIVE_SEGMENT.. (here unable to sender cost center field and the receiver cost center field)

                           FAGL_COFI_ACCIT_MOD.. (here we get only sender cost center field not the receiver cost center field)

one exit :EXIT_SAPLPC02_001, (Here also unable to sender cost center field and the receiver cost center field)

could you please help for the above post...

Thanks in Advance
