backorders

We have orders going directly to backorder without us seeing them and so we don't know they are out there and cannot respond. How can we deal with this?  We want to see every item on an order when we go to pull it regardless of whether it is backordered or not.  when our distribution techs are using their handheld mobile supply units and are pulling the orders we want them to see the backorder items at that point as they are standing at the shelves pulling orders
