After a prebook is created the system automatically adds the items from the Prebook into a “needs” list of items that need to be purchased.
As items from the "needs" or "purchasing" needs are added to a purchase order they are automatically removed from the “needs” list. This allows a company with multiple users in procurement, to purchase product only once.
In order to create purchase orders from Prebooks, there must be Prebooks created in the system.
