 Backflushing Locate this document in the navigation structure


A goods issue has to be posted for every material that is withdrawn during order processing. This can occur at the following times:

  • Directly as the goods are issued

  • When the operation is confirmed, the materials assignd to the operation have the goods issue posted. this is known as backflushing.


You decide whether a material can be backflushed in three different places. These are the master records of

  • The routing

  • The material master

  • The work center

If you set the Backflush indicator in the routing, the material is always backflushed regardless of what you entered in the material master record.

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

In the graphic you can see which indicators you have to set and where to control backflush.
