Change the Quantity Ordered to a higher number, which will open the BO Field.  Set the BO Quantity to zero.  Then edit the original quantity ordered to what it was when you started.  Save the PO.  If the Quantity Ordered = Quantity Received = Quantity Invoiced, the order should now be in a COMPLETED Status.  If the Invoice was not received, then it is still a backorder and the invoice needs to be received for three point matching.
