In this field in the Electronic Receipt Posting window, specify whether you want the system to add filled items that are on the invoice but do not match to any items on the PO(s).
Y = Append (add) extra items to the target PO. (note: if you use a blank PO to post to, use this option.)
N = Do not append extra items to the target PO. If you use this option, you must manually add the items to the PO in the Purchasing and Receiving window.
A = Append extra items to the target PO even if the vendor of the items doesn’t match the PO’s vendor.
This field defaults to N.
