A Quantity exception occurs when the quantity invoiced by the vendor is more than the quantity in the order.
As you can see in the example above. The Invoiced quantity is 11 and the ordered quantity is 10. Assuming you are OK with the invoiced quantity, the exception can be resolved as follows.
There are two ways to resolve this
1. Withdraw the invoice from the approval process, and change the order to adjust the quantity as per the quantity invoiced by the vendor. After changing the order, resubmit the invoice for matching by clicking on the Submit button.
2. The other way to resolve this exception is to approve the invoice exception. The system automatically routes exception for approvals based on review workflow.
