Qty billed exceed Qty Recieved -- Hold in AP is driven by Which Checks /Setups

 Hi All

What is the logic that puts Qty billed exceed Qty Recieved -- Hold on Ap invoice

As we are having AP invoices even when we match the Invoice to receipt and change the qty while matching to Invoice

System does not put the hold  Qty billed exceed Qty Recieved 

which should come after Invoice validaton

But when we match to PO system does not allow to change the qty on AP Invoice while matching

I believe we are missing  some integral setup

Thanks,

Sheetal
