Over Receipt tolerance is ignored while receiving

Hello,

I have created a PO Requisition in I-Procurement for 10 quantity. While creating a receipt I entered the quantity as 50 instead of 10. The system warned but did not stop from creation of  Receipt.

Referred to

Why Is Receipt Tolerance Not Considered And Over Receipt Quantity Is Allowed? (Doc ID 433373.1)

The setup is already there as per the above note i.e. 'Allow Blind Receiving' is unchecked.

However, still the system does not restrict. We are using Oracle R12.1.3

Also referred to Bug 6070256 : WHILE CREATING RECEIPT,TOLERANCE IS NOT CONSIDERED & OVER RECEIPT QTY IS ALLOWED

Any views ?

Thanks
