A gods issue has to be posted for every material that is withdrawn during order processing. Goods issue posting can be carried out:

• Directly when the material is withdrawn

• At a later date, that is, when the phase to which the relevant material component is assigned is confirmed. This is known as backflushing.

To determine whether a material is to be backflushed, you can make settings in the:

• Material master record (MRP view)

• Resource (Basic Data screen)

• Master recipe (General Data screen for component assignment)

• Process order (General Data screen for the material component)

When you create a process order, the settings made in the master recipe are copied to the order. However, you can still change them.

If you set the Backflushing indicator in the process order, the material is always backflushed regardless of what you entered in the material master record.

If you do not set the indicator in the process order, whether the material is backflushed or not depends on how you set the indicator in the material master record.

In the material master record, you can determine whether the material is always to be backflushed or whether it depends on the settings in the resource.

The following graphic shows where you must set which indicators to control backflushing.

Maintain the indicator for backflushing:

• In the material master record, if you always want to backflush the material

• In the master recipe or process order, if you only want to backflush the material from time to time
