In Customizing, you must set the optional reporting point backflush.

• Using the optional reporting point backflush, you can backflush assembly scrap up to a reporting point. The system then subsequently backflushes the yields for all previous reporting points.
• In the assembly backflush, you can also backflush component scrap at the reporting point. The system then does not post the specified quantity as assembly scrap but as excess component consumption. The system also posts the production activities for the assembly of the components. You select this indicator if the components required for the production of the assembly at the current workstep have been damaged.

4. You now have various options:

The reporting point backflush creates a document log with the following individual documents:

• Reporting point document for the successfully carried out goods issue postings for the components.

• Activity document(s).

• If necessary, postprocessing documents for the unsuccessful goods issue postings.

If you use the simplest variation of the optional reporting point backflush, no quantities are backflushed at the reporting points and you post the goods receipt manually. This scenario corresponds to a backflush with no reporting points.

You receive a backflush document and a material document.

Scrap up to the reporting point is the scrap quantity produced by the end of a backflushed reporting point operation. The yields and the components from all previous reporting points are backflushed subsequently.

In this example, a scrap quantity of one piece up to reporting point 30 is posted.

You receive a backflush document, a material document for all components, a scrap document and a yield document for the reporting point.

The WIP backflush is a stock balance of the materials on the production line at the reporting points. This backflush is mainly carried out for Controlling which calculates the valuated stock.

Here, the reporting point quantities are backflushed in the same way as the mandatory reporting point backflush.

When balancing stock at the end of a period (inventory), all materials on the line are included. That is, all materials between the reporting points. The reporting point quantities in the SAP system, on the other hand, correspond to all quantities of materials that have passed through a reporting point.

This view is created in the WIP backflush in the system. This example shows the actual situation (that is the current stock on the production line). Two pieces are on the production line at reporting point 30. In the next step, two pieces are subsequently posted at all reporting points. Three pieces have passed through reporting point 20 meaning that three pieces can be subsequently posted for both reporting points 10 and 20. One piece is on the line at reporting point 10 where it is subsequently posted.

At the beginning of a new period, the reporting point quantities must be returned to zero so that the initial situation is achieved and so that further goods receipts can be posted. The goods receipt is two. The two completed materials are subtracted from the reporting point quantities. At reporting point 30, a quantity of 4 is subsequently posted and at reporting point 20 a quantity of 1 is subsequently posted. The reporting point quantities are reduced to zero with the next goods receipt of 4 materials.
