Verify Duplicate PO Numbers for A/R Orders (D80)

Purpose: Use this screen to define whether to verify that each purchase order number a customer uses is unique.

Yes/no field: Select this field if you want to verify that each purchase order number you enter on an order from a sold-to customer is unique. See Selecting Customers in Order Entry.

Note: Purchase order numbers are usually used for accounts receivable orders (payment category = 3) but you can use them for any payment type.

If you enter a duplicate purchase order number for a customer on either the order header or order recap screen, the following message displays:

PO# (xxxxxxxxx) already exists on another order for this customer.

Similarly, if you process an order with a duplicate purchase order number through the e-commerce interface (order API), the order goes into error status, with an error of Duplicate PO#.

Leave this field unselected if you do not want the system to validate that purchase order numbers for a customer are unique.
