VP tolerance check not working during GR

Configuration in VP:

Lower Limit Tolerance: Do not Check
Upper Limit Tolerance: 2%

Message:

M7 306 and M7 307 has been set to Error in OMCQ

Issue:

Material Price before PO - $6
Stock beore PO - 100
Stock Value before PO - $600

Order Quantity - 100
Purchase order Price - $25

Now the new price after GR will be $15.5 = ((100 * $25) + $600) / (100 + 100) which is almost 158$ increaase that is beyond the upper limit tolerance of 2%.

But there is no message popped up in MIGO (when doing the check and post) as well as in MB01.

Also during invoicing, it does not pop up anything.

Question:

The Percentage increase should POP up atleast a warning message during MIGO regarding the price increase.
