Use this activity to change the quantity of a purchase part if you want to substitute it with an approved alternate part. This feature is useful if, for example, you are informed by a supplier that he or she cannot deliver the required part in time but that other parts are available as substitutes.
Note: Alternate parts cannot be specified for purchase orders with order code 6 (External Service Order), nor for purchase order lines showing a value in the Cust Order No field.
The original part order line will have its quantity changed to the value you enter in the Add/Change Alternate Parts dialog. If the quantity is changed to zero (0), the line will be canceled.
The alternate part(s) for which you have entered a new quantity will be added to the purchase order, and the original part number will be added as a reference to the lines.
