CRE LOADED - Add Backorder indicator in Order Details

Increment 1: ============ Add backorder indicator in the order details in admin, order email and invoice. This will indicate which out of stock items have been purchased by customer knowingly, and, will be shipped later. Increment 2: ============ There is a 'Low Inventory' report that displays items below 'Re-order level'. I would like to have a new (or update same) screen that displays the low inventory information (exclude Inactive). With following features: - A Qty column to allow updating the product qty in bulk. All columns are small product image, product number, qty in stock and update qty. - A print button to print the 'Low Inventory' report, it should not display 'Inactive' products. - A print button to print inactive products report. - Screen/Report should display following columns: Product Number, Small Product Image, Qty in Stock Feel free to ask any questions you have.
