| # Manually Backflushing Materials and Hours Before backflushing the operations, you must select the operations to be backflushed: For single production orders, select the production orders and operations to be backflushed. For production orders in an SFC order group, select the SFC Order Group check box and enter the order group. The fields in the Selection Range group box determine the production orders that are backflushed. Production orders for repetitive items are only backflushed if the repetitive item's scheduling area is within the selection range. The fields in the Settings group box specify further which operations are backflushed. These settings are not available if you are backflushing orders in order groups. LN records which quantity of a product has already been backflushed. This action guarantees that each quantity of a product is backflushed only once. If the Backflushing Method parameter field in the Shop Floor Control Parameters (tisfc0100s000) session has the value Automatic, the Backflush Materials and Hours (tisfc0220m000) session has no effect. When automatic backflushing is applied, each quantity of a product is backflushed immediately after it is reported as completed or rejected. You can backflush a production order from when the production order is released until it is closed. You can enter a date in the past in the Backflush Date field, if you want to apply antedating.
