Payables Sources for PO to Invoice differences

Summary

Capture Variance amounts (PO to Invoice) for Quantities, Amounts

Content

Hello,

We have a need to capture the differences for quantity, price and amount when matching AP Invoices to Purchase Orders and Receipts.

We attempted to use the following Sources available to the Payables Event Classes but they do not pick up any values.  I am not getting much help from support so I figured I would try here.

Here are the sources:

AID_AMOUNT_ENCUMBERED	Invoice Distribution Amount Encumbered	Number	Encumbered amount of the invoice distribution.
AID_AMOUNT_VARIANCE	Invoice Distribution Variance Amount	Number	Variance amount for invoice distribution lines matched to purchase order or receipt.
