Salesperson
The salesperson who sold the order is displayed. This field is used when calculating commissions for each salesperson. The default entry for this field is the salesperson entered on the Customer Ship-Tos form for the customer specified on the customer order header.
Note: You can only save changes to the Salesperson field when zero or one commission
distribution records exist for the current customer order. If two or more
exist, then you will receive an error and the save action is disallowed.
If one commission distribution record exists, the system will change the
salesperson on the current record to be the same as the new salesperson
on the customer order.
