Bank Charges on Receipt functionality - Oracle Receivables 11i

A situation arises where a payment made by a customer via a Bank Facility sees the bank deduct a commission for the payment handling with a bank fee. From the customers point of view, the debt has been fully paid and this should be reflected in Oracle as the debt being fully extinguished, however, the receipt provided by the bank does not meet the full invoice amount. I am trying to determine the best way to have receivables handle the following example.

Customer has an invoice and total debt outstanding of $100. The debt is paid via a bank transaction for which the bank charges a fee of $10 that the receiving organisation is prepared to accept.
