PO Over Receipt Tolerance

Hey everyone.

Is there any way to allow an over receipt on a PO so that the PO does NOT close automatically after doing so?

We have one vendor we would like the PO to remain open as they are sometimes overshipping, which is ok, and it is critical that the inventory receives in smoothly.

Since the PO is closing once within tolerance or over the ordered amount it is causing issues in the warehouse. The receipt itself is automated via the RHI/RTI interfaces, and we are sending out notifications when the receipt tries to come in that the PO is closed, but the warehouse personnel aren't always catching it in time before we need the inventory.
