When a PO Invoice detail line is matched for less/more cost than the PO Receipt was processed for, how does the system handle this cost variance?

Occasionally, the cost being charged (invoiced) by the supplier is different than the cost entered for a PO Receipt.  Normally, these variances are not too large unless a supplier begins charging a cost much different from what you anticipated.

When this variance occurs, the system handles the variance by posting it to your RNI Adjustments account, whenever that particular PO line is closed.
