Backflushing (PP-REM)

Purpose

You use this component in Repetitive Manufacturing to record work process in the system. Backflushing is a very lean process, corresponding to the requirements of repetitive, mass or flow manufacturing. For example, you do not have to post any of the actual production data until posting the goods receipt of the finished product in a final backflush. In make-to-stock repetitive manufacturing, you can also backflush at the reporting points of predefined operations. This enables you, for example, to determine the stock of unfinished products in production.

In the final backflush, you can link the following processes:

Posting goods receipts for finished products
Posting goods issues for the components
Reducing planned orders or run schedule quantities
Posting production costs to product cost collector
Updating statistics in the Logistics Information System (LIS), such as goods receipt statistics or material consumption statistics.

Furthermore, you can separate these processes to backflush high volumes of data with low response times.

Integration

Backflushing is an integral part of repetitive manufacturing . Backflushing is directly linked to Periodical Product Cost Controlling via the Product Cost Collector.

Features

Depending on the type of repetitive manufacturing you use in your business ( Make-to-Order Repetitive Manufacturing (valuated stock), Make-To-Order Repetitive Manufacturing (non-valuated stock), production by lots or Make-to-Stock Repetitive Manufacturing), you have the following options for backflushing:

Final backflush

You use this function to carry out the final backflush at the end of the production process. You can carry out goods receipts for stock materials, with reference to a sales order or to a production lot or for a KANBAN material even if the material was produced at another plant.

Reporting point backflush

You use this function for make-to-stock REM for backflushing unfinished materials (work in process) at predefined operations. You use the reporting point backflush in the following situations:

To calculate the quantity of semi-finished products in the production process.
To post the goods issues of components closer to the actual withdrawal of the components when working with lengthy lead times.
If you want to backflush scrap quantities at the corresponding operation.

You can define whether reporting point backflushing is mandatory or optional.

Separation of backflushing processes

If you want to backflush high volumes of data, you can significantly cut system response times by posting the goods receipt immediately and then posting all other data later.

Backflushing several materials collectively

You use the collective entry to backflush several materials together.

When backflushing in make-to-stock repetitive manufacturing, you can backflush several materials collectively. For example, you can backflush all materials on one production line simultaneously.
