Lines that can be matched
For a purchase order or invoice line to be matched it must be at a stage where it is available for invoicing. That is, lines with an Invoicing Status of either Available for Invoicing or Part Invoiced can be matched; lines with a status of Fully Invoiced, Not Available for Invoicing or have a Purchase Type where invoicing is not a defined stage, cannot be matched.
The invoice line contains a Matching Required check box. If an invoice line does not require matching even though it is a stage on the purchase type, matching can be bypassed. This allows for lines that appear on the invoice but do not exist on the original purchase order and do not require matching. For example, carriage charges.
