Setting a receipt tolerance to autoclose order

Summary:

I am testing setting up a receipt and invoice tolerance for fixed price services, goods and rate based services.

The Purchasing line type is set to 3 way match, the customer wants the order status to update globally to closed for receiving when the receipt is within 98% of the total order value. and the same for closed for invoicing.

I am initially testing the closed for receiving by setting those tolerances before moving on to include the invoicing.

However, when I set the purchasing line type tolerance to 98% and set the receipt close tolerance % in Configure Procurement Business Function to 2% but the orders are not updating when testing. (I also tried matching the %'s)
