Hi, 

I get the issue, 

What is the real concern? I suspect the received not invoiced report shows erroneous data. 

If that’s the main concern, you can probably - simply enter a close date on that receipt record. That close date takes the record off received not invoiced report.  Sure, matching is wrong, the price per unit (as calculated) is wrong, but if your using STD cost, it did not affect inventory.  

I have not tested, so I don’t have a clear view of all your concerns / all things that are “wonky” due to the matching issue. So many things can affect the full nature of the issues.  For example, assume part cost was 1 mathematically the incorrect nature of the cost is immaterial / probably not worth fixing.  You could simply fix the cost. 

Best regards, 

Thomas
