Why do some PO Lines not appear on the Purchase Invoice?
Purchase Order lines which are completed will not appear in the Enter Purchase Invoice window.
The Purchase Invoice window only includes lines that have not been completed on the Purchase Order.
Completed lines on an open PO are hidden by default but can be viewed by clicking the "Show completed lines" checkbox.
PO lines are marked completed when the line has been received in full and invoiced in full.
Drop Ship, non-inventoried, other charge, shipping, labor, and non-standard lines cannot be received therefore invoicing the full quantity of the line will mark it as completed.
