Unmatching a purchase invoice

You can unmatch an invoice line that has been matched to an order line in error.

For an invoice line to be unmatched, it must fulfil the following criteria:

  • The invoice must be matched to one or more orders.
  • The invoice line must not be closed.
  • No receipts (that is, inventory updated) can have been created at the matching stage.

An invoice line is closed when the last mandatory stage defined in the Purchase Type has been fully completed. You can see if a line is closed by checking the Status field on the invoice line.

Note:  If unmatching is to be used, another stage (such as the Invoice Confirmation or Receipt Note Entry/Matching stage) must follow the Invoice Matching stage, as this will stop the line being closed immediately.

When unmatching, the following occurs:

  • All order lines that the invoice line is matched to are unmatched. You cannot unmatch an individual order line.
  • Any ledger postings at the invoice matching stage are reversed by an opposite ledger posting.
  • The matching flags on the order and invoice line are reset.
  • Any budget expenditure and budget commitment entries are reversed.
  • The latest/actual cost on the receipt is amended back to its original value before matching. Any related issue records have the cost change rippled through them. Item costs with analysis are amended. If part of the order line being unmatched is matched to another invoice, then that invoice cost is used, otherwise it is amended back to its original order value before matching. However, the system-wide item cost (that is, cost without analysis) is not updated, as too many other transactions may have affected this cost between invoice matching and unmatching.
  • The adjustment made to the weighted average cost at invoice matching is reversed. Any related issue records have the cost change rippled through them.
