Before you begin this process, you must TAKE AN INVENTORY CYCLE COUNT
Once this is done, create a purchase order by selecting a menu(s), and clicking "Purchase"
Once inside of the "Purchasing" page, click "Select Cycle Counts". Then, check every Cycle Count that applies to the purchase order and click "Save". The "On Hand" amounts from the Cycle Counts will then be subtracted from what is needed to produce the menu(s). The remainder is the "Order Amount".
