Two-way net unit price matching
Two-way matching helps you make sure that the variance between the price information on the purchase order and the invoice is within acceptable tolerances. You can compare price information for the net unit price of each item on the invoice. This process is called net unit price matching.
You control two-way matching for the legal entity through the Line matching policy field on the page. Depending on the selection in the Allow matching policy override field, you can select two-way matching for a specific vendor, item, or item and vendor combination on the Matching policy page and for a specific purchase order on the Purchase order page.
The Enable invoice matching validation field on the Accounts payable parameters page controls net unit price matching. You can configure the net unit price tolerance percentages for items, item groups, vendors, vendor groups, item and vendor combinations, or legal entity by using the Price tolerances page.
