<BO> = Back Order: You may automatically create a back order for the Order before it is Finalized. The Quantity Back Ordered will be calculated from the Quantity Ordered minus the Quantity Shipped. Once Finalized, the Back Order process will work as usual. This option must be setup in “POS Defaults & Comments” in SYSTEM MANAGEMENT (10.2.6.2 field 9 page 1).

Password protection for this feature is found in "POS Passwords" System Management (10.2.6.3 field 29 page 2).
