Before routings are archived and deleted, the system checks for the following usages:
- Usage in a production version
The routing is stored in the material master record as a part of a production version.
- Usage in an inspection lot
This criterion is only relevant if the Quality Management System (QM) is active in your system. You can only archive a routing if it is no longer used in an inspection lot.
- For reference operation sets/reference rate routings: References in routings or rate routings
You can only archive reference operation sets or reference rate routings if references to other task lists no longer exist.
- Usage in a run schedule header
A run schedule header always requires information from its routing, for example for confirmation. You can only archive this type of routing if the run schedule header is complete and archived.
- Other usages which you can define using the SAP Enhancement CPRE0001
Therefore, the archiving functionality for routings is dependent on the following objects:
- material master records with production versions
- run schedule headers
- inspection lots (archiving object QM_CONTROL)
What Happens If a Routing Is Still Used
If during the usage check the system finds a routing which is still being used or which meets the checking criteria you specified (with SAP Enhancement CPRE0001), the system responds in one of the following ways:
- The archiving run is terminated. You receive an information message with the routing which is still being used. Do not set the Log indicator in variant maintenance for this result.
- The archiving run is completed and then you receive a log with a list of all routings which could not be archived or deleted because of the usage check.
Set the Log indicator in variant maintenance for this result.
