Forum Post: Prevent users from changing unit of measure on receipt

Hi all, on GP 10 how can I prevent the users on the wrehouse to change the unit of measure on the receipt? can it be done that it's locked to the unit of measure the purchase order was entered?

I mean, user 1 enters a PO with a line:

Item        UofM     QTY      Price

Pencil     box10        1        10.00

I want the user thar enters the receipt to only be able to receive box10 and not use any other UofM, is this posible on GP? also so they can't receive more than the qty specified on the PO.
