The IAConnect Invoice Matching settings determine the way the Workflow approval process interacts with the Costpoint purchase order line information. Each purchase order line has a 2-way or 3-way match designation. An overage mismatch can occur when either the Receiving or the Amount in the ERP is not matched to the invoice and is performed as follows:
-
3-Way matching validates that the PO line Remaining Quantity, Accepted Quantity (or Received Quantity, if configured), and Invoice Quantity are all in alignment.
-
2-Way matching validates that the PO line Remaining Amount and Invoice Line Amount are in alignment (no receiving requirements).
-
If the invoice input is greater than the PO remaining balances or if there is no receipt information, then there is a mismatch and the invoice is routed to the PO Mismatch queue. If there is no mismatch, the invoice bypasses approval and is moved to the Final Review Queue.
To use Invoice Matching, enable the PO Matching Enabled option. When this is enabled, both 2-Way and 3-Way matching are enabled for any jobs included in the Job Queue Configuration in the IAConnect Queue Configurations tab in Customer Configuration. for more information on this, see Job Queue Configuration.
Under 2-Way Comparison Options, you can choose to include tax in the matching calculations by enabling the Is Tax Included option. To determine which quantity is used for 3-Way matching, choose either Accepted Quantity or Received Quantity from the 3-Way Matching Type drop-down menu.
The 3-way match is typically based on the Accepted Quantity. However, the 3-way match can be configured to use either the Accepted Quantity or the Received Quantity.
