Payables Entry Improvement

Dear All,

I need to separate an amount that goes to a gl account after write off when applying manual payment to an invoice. This amount goes to one account but its required to be apportioned to two accounts.

i.e

DR the first account (On posting account set up for write offs) to eliminate the amount

CR  the second account

Credit the third account

All of above should create the batch and affect the payable distributions table.

Any help please????
