Esettlements Supplier proposal discount not equal to discount applied on PeopleSoft voucher for Self

 

When a Supplier proposes a discount, the discount that is seen on their end is based on Gross Amount.  When we accept their discount proposal as Buyers in PeopleSoft, the discount is calculated on Merchandise Amount.  Is there a configuration somewhere that we can change to reflect the same discounts at both parts of this process?

Thanks, Jensco
