You can use the component backflush (also goods issue backflush) to carry out the following business functions:

• Posting excess component consumption / scrap.

Using the component or activity backflush, you can post components or activities separately.

The separated component and activity backflush is only possible with make-to-stock repetitive manufacturing.

If you want to backflush finished products and, at the same time, components and activities, switch to the assembly backflush.

You must create a product cost collector.

The following functions are included in the standard version of the goods issue backflush:

• The system posts the goods issue.
• The system determines the components by exploding the current BOM, the revision level BOM, or the planned order BOM.
• The system reduces the planned orders or the run schedule quantities according to the logic set in Customizing for Repetitive Manufacturing.
• The system updates the statistics for the Logistics Information System (LIS).
• The system creates individual documents for each posting as well as a full document.
