If error postings occur, you can reverse the backflush.

When you carry out the reversal, the full backflushing document (which acts as a bracket around all the individual documents) is flagged as reversed, along with the following data:

• The goods receipt is reversed and the accompanying material document and full backflushing document are indicated as cancelled.

• The goods issues for the components are reversed, that is, the component quantities are posted back.

• The activities are reversed.

• Depending on your settings in the repetitive manufacturing profile, the system proceeds as follows to cover the reversed quantities:

• The system either creates a planned order for the reversed quantity.

• Or, it activates a single-item planning run which creates a planned order that corresponds to the possibly changed planning situation.
• Or, the system does not create a planned order in which case the planner has to check the situation.

• The basic dates are determined for the newly created planned order.

• If you set the system to create an individual document for each backlog in the repetitive manufacturing profile, then the system deletes the corresponding individual documents and adjusts the quantity accordingly in the cumulative log document. Moreover, postprocessed backlog postings are reversed.

• The Logistics Information System is adjusted.
• In the separated backflush, the planned order is increased by the corresponding reversal quantity.

In some areas, for example, chemistry, it can make sense to backflush required quantities in advance, without naming specific quantities. The actual quantity used is only measured after production, using precise measuring equipment. The required quantity must be corrected afterwards.

To do this, you can carry out a partial reversal with adjustment to individual components. In the initial screen for backflushing, choose Document-neutral reversal. The system automatically switches the movement type to the reversal movement type if you have made the corresponding settings in Customizing.

You now have all backflushing functions at your disposal, but with reversed postings (for example, adjustment of individual components).
