| # To match purchase invoices automatically To match purchase invoices automatically, in the ACP Parameters (tfacp0100s000) session, select the Automatic Matching check box. You must select a matching method, which can be Match to Purchase Receipt or Match to Purchase Order. If you set up automatic matching, ERP LN automatically tries to match purchase invoices that you register in the Purchase Invoices (tfacp1110s000) session. You must select the purchase order or a packing slip with which the invoice can be matched. If ERP LN cannot match the invoices automatically, for example, because the purchase invoice refers to multiple purchase orders, you must manually match the invoice as described in To match purchase invoices manually. ERP LN matches the purchase invoice with the unmatched quantities of the receipt or the purchase order, depending on the selected automatic matching method. ERP LN calculates the total amount of the matched quantities and the difference with the entered invoice amount in the Amount Unassigned field. If no difference exists or the difference falls within the tolerances, the invoice is successfully matched. The difference is posted to the Price Differences account of the financial business partner group. If the price difference exceeds the tolerance, it must be authorized in the Authorize Purchase Invoices (tfacp1142m000) session before you can approve the invoice. For details, refer to Authorization of price differences and additional costs. If the invoice is partially matched and more goods covered by the invoice are received at a later time, you can manually complete the matching and approval of the invoice in the Match/Approve Purchase Invoices (tfacp2107s000) session. If the invoice is fully matched, you can approve the invoice as described in To match purchase invoices. Related topics To process purchase invoices To match and approve purchase invoices |
