In OIC, Sales credit to be provided to the collector of the payment in AR

Hi ,

In OIC,

     The sale is done by a salesperson, he is identified in the Sales Order and raised an invoice under Receivable.

      He gets the full commission on the sales credit

Now for recovering the amount, the collection person is assigned from the the collection team.

     After the payment to the sales order invoice is received in the receivable, the commission for the payment should be paid to the collector only and not the salesperson for the sale

Please help, since in oic only salesperson of the sales order comes as eligible for the commission for the payments in the receivable.
