Assembly backflushing

Floor stock items such as nuts and bolts are not backflushed in assembly control. To define an item as floor stock, select the Floor Stock check box in the Item - Warehousing (whwmd4600m000) session.

Backflushing is carried out for each clustered line-station order (CLSO) (see the Clustered Line Station Orders (tiasc7530m000) session). The number of CLSOs produced each day, depends on the mode you select with the Transaction Processing parameter, which you define in the Assembly Control Parameters (tiasc0100m000) session. For Order Based processing, each individual assembly order provides a CLSO for each line station, creating many CLSOs each day. For Line Station Based processing, there is only one CLSO each day, for each line station. All the hours and materials for all buckets, all line-station variants, and all line-station orders are clustered into one CLSO for each line station. This mode is for high-volume production environments.

The parts required by the line station variant can be backflushed after the line station order is reported complete, with the Backflush Requirements (tiasc7241m000) session. The quantities required are calculated as described for the Build Assembly Part Allocation (tiasc7240m000) session. LN activates a warehousing order line which ensures the parts are delivered to the correct shop floor warehouse.

Floor stock items such as nuts and bolts are not backflushed in assembly control. To define an item as floor stock, select the Floor Stock check box in the Item - Warehousing (whwmd4600m000) session.

Man hours (also known as person hours) and machine hours are backflushed to People.

If hours are present, the hours transactions with the status Closed are posted to People and processed automatically. The hours are posted to the employee linked to the line station. You can view the hours with the Assembly Hours (bptmm1160m000) session. You can also enter additional hours with this session.

The values that are visible in the Clustered Line Station Orders (tiasc7530m000) session are used by Warehouse Management. When material backflushing is performed, the inventory for the assembly part is backflushed from Warehousing, and the Planned stock transactions in the Order - Planned Inventory Transactions (whinp1501m000) are reduced.
