Maximum/Quantity Received Tolerance Setup

Hi,

Regarding the setup of AP Tolerances I want clarification for the setup of Maximum Qty Received and Qty Received Tolerances.

As per the user guide:

Maximum/Quantity Received. Enter either the percent or quantity difference above purchase order shipment line quantity received that you allow suppliers to invoice. Approval checks the quantity billed against the quantity received without taking price into consideration. Enter a Maximum Quantity Received quantity tolerance only if most of your purchase orders are for the same relative value.

DO THIS MEAN THAT ONLY ONE SHOULD BE SETUP?

Thanks,
