When pricing is added to a PO that has already been validated, we receive a prompt to resend the order for re-validation. I think it can be confusing when only the rate is being added and may lead to unnecessary additional validation costs if, to be on the safe side, "send for revalidation" is selected. This message should appear if there is a change to the unit of measure but, not if a rate changes. For example: Changing from $0/YD to $6.50/YD has nothing to do with the quantity that is validated.
