You can check back orders in a couple of ways. First if you go to Reports -> Report/Lists -> Creditors -> Back Order List and run the report, it will tell you what's items are on back order. You can also go to Creditors -> Orders -> Clear Back Orders -> Clear All back orders. This just opens up the oldest back order so you can see what your waiting on. The items on back order will have a quantity in the Qty BO column. If the order actually isn't still on back order you can click the SF10: Clear B button to clear it. Otherwise click the scroll buttons in bottom left hand corner to check other back orders.
