Credit card Deposit on banking

Dear Experts,

My company used deposit module to declare credit card settlement, but how to make the comission was included into nett bank account, not put in separate journal.

eg. SAP journal

Bank A 100

AR Credit Card 100

Comission 2

Bank A 2

should be ;

Bank A 98

Comisison 2

AR Credit Card 100

if i used the SAP journal, it will very difficult to make the reconciliation since we received from the bank the nett amount. Any one knew how to solve this matter?

Thanks
