Amount based Tolerances For credit memos does not work

Summary:

The use case is as below

1. We issue a negative PO to the supplier for returns
2. Supplier sends a credit memo
3. Match credit memo to the negative PO
4. Invoice ( credit memo) is not going on hold
5. Amount based tolerances defined for Ordered % and Maximum ordered amount

Is the reason because its a credit memo and Tolerances only apply when Invoice qty/price/amount is more than PO qty/price/amount but in this case its a credit memo invoice
