Receipt tolerances and invoice lines
A receipt tolerance sets a limit for the quantity or the amount that can be invoiced for a service line item or a standard service line item. The receipt tolerance is set for an item in the Item Master application. The receipt tolerance can be modified in the purchase order.
If the quantity or the amount of the line item received exceeds the receipt tolerance set for that item, you can invoice the item up to the receipt tolerance amount or up to the quantity set. If you cannot receive any service line items in excess of the ordered quantity, you must modify or delete the associated line item.
