Change the information on the invoice and process the invoice again.
Explanation: Because commissions are calculated by the system at the time an invoice is processed, changes to the commission calculations can be made by changing the information on the invoice and processing again. Open the invoice associated with this commission. Record any changes necessary to alter the commission amount of the order (additional costs, commission percentage), and process invoice again.
