The Backflush Materials check box in the Production Orders (tisfc0101s000) session. You can modify these check boxes for a particular production order. LN backflushes the material only if you select both of these check boxes. If you clear the Backflush Materials check box, LN clears the Backflush Materials check boxes for all materials.
