Voucher match for partial Non stock PO with updating the quantity and amount

Hi,

We have a case where we creating a non stock Po with order quantity and doing partial voucher match by updating the amount and quantity. But after the voucher, the open amount yet to voucher is showing more than what we ordered.

ex: Order value = 1,968,000 with qty 1

Voucher booked= 116,512 with qty 0.059

The remaining amount should be 1,851,488.

But the open amount for voucher match is showing 1,851,888.

Is there is any workaround for this case?

Thanks,
