It is common practice in many European accounting environments to book invoices into the system immediately on receipt of the supplier’s document, and to account for taxes immediately. The Unmatched Invoices account is used for these purposes.

Standard supplier invoices generate two sets of postings:

When you create a standard invoice for matching, the system creates invoice postings to the supplier control and Unmatched Invoices accounts (and tax accounts, if tax is applied). These are displayed on the SI Posting tab once you have completed the key fields on the General tab.

You can modify SI postings before saving the invoice, by changing the tax conditions or invoice amount on the General tab, but once you save the invoice, these postings are booked to the official layer and cannot be modified. The receiver amounts must then equal the total of the invoice amounts posted. See SI Posting Tab.

Current invoice SI postings are also booked to the official layer when you click the Matching button to begin matching. The Matching Posting tab of an invoice that is to be matched is not available when you start the matching process. Matching postings are generated and the tab completed only when you have saved the matching with a status of Finished. See Matching Posting Tab. The GoTo option within Receiver Matching Create lets you view the invoice in a new window and confirm the matching postings after completion. In addition, Supplier Invoice Create remains open when you start matching an invoice, and you can then use Ctrl-B to refresh the view, and examine the Matching Posting tab. In Receiver Matching Create, you can use Ctrl-B to refresh the view when a matching is saved with the Finished status. You can then click the Manual postings button, which shows the matching postings.
