The Backorder List window enables you to choose how to handle the situation where you want to sell more items than you have on hand.For example, if you enter 1,000 in the Ship column on an invoice but only have 500 of the item on hand, this window will appear when you click Record in the Sales window.You can use the Backorder List window to perform the following tasks: build, buy or backorder. However, you can only perform one of these tasks at a time and in the following order: build, buy and then backorder. For example, if you want to backorder some items and buy others, you need to buy the required items first and then return to this window (by clicking Record in the Sales window again) to complete the backorder.
