When you attempt to record a sales invoice with an insufficient on-hand quantity, the Backorder List window appears. In this window, you need to build or buy the required quantity or create a customer sales order (backorder) for the unavailable quantity, before you can record the sale.
Before you can auto-build an item in the Back order List window, you need to set up your item details. For more information, see
Auto-building items.
You can use the Backorder List window to perform various tasks. 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.
