PO Number
If you are entering a receipt of a single purchase order, type the purchase order number or select the number from the Finder of the vendor’s purchase orders.
If you specify a single purchase order number in this field, you will not be able to use the From Multiple POs field.
You do not have to specify purchase order numbers with receipts. However, if you do specify a purchase order number, the purchase order details are displayed and you cannot add new details or receive a quantity that is greater than the quantity ordered on the purchase order.
The Finder for this field shows only incomplete purchase order numbers. (You cannot post receipts to completed purchase orders.)
You cannot change the purchase order number after posting the receipt.
