Hi Sruthi,
FP40 can't be used on different divisions.
Another approach to achieve it is say debit charge need to be transferred from source to target account.
Through FPE1 post credit on source and debit on target account using same main,sub and company code in one shot , so the net effect will be Credit AR and Debit AR(Zero), not posting against any other accounts.
Thanks,
Vikram
