The sales reps are initialized by the customer sales reps, then by those of the ship-to customer, if no sales rep exists in the customer record. If one of the two sales representatives is modified and if there are lines in the order, the system will ask the user whether to copy the modifications to the order lines and to recalculate the commission rate. The user will also have the possibility to only modify the order lines referring to the previous sales rep code (choice Yes if same Value).
