On the same invoice, you can dispute some exceptions and accept others. By default, an Invoice Reconciliation (IR) document that contains disputed items can be approved. In this case, the invoice is short-paid and the supplier must submit a corrected invoice for payment of the disputed items.

By disputing an invoice exception, you are saying you will not pay the invoiced amount for that particular item. By default, when a user disputes an item, the values on the original purchase order (not the values on the invoice) are marked for payment.

For example, if the quantity invoiced is greater than the quantity on the purchase order, when the IR document item is disputed, the quantity value will default to the number on the purchase order. The user with the proper permissions can also change the value to another number before the IR document is submitted.
