First, we are set up to allocate by Line Item and to transfer orders to back orders and back orders to orders.
Second, our customer orders typically consist of multiple line items (which are often BOMs). When one of those line items cannot be allocated (because we don't have the inventory on hand) and we transfer the item to a back order, can that back ordered item be transferred back to the original order (the one with the rest of the line items) when the back ordered inventory is received? Or, does GP create a new order for any back orders that are transferred to orders? Basically, we want to keep the ordered line items together so we would like to figure out how to transfer the back order to the original order.
