Deletion of Production Resources/Tools 
Use
You can use this function to delete production resources/tools (PRTs) that are no longer available in the system. You then prevent them from being used in routings and orders.
Features
There are two main functions for deleting master records:
You can only use this function for production resources/tools with a PRT master record (miscellaneous).
Immediate deletion can only be carried out if the production resource/tool:
The production resources/tools are deleted logically, that is, you can no longer access their master records. However, the master records are still physically present in the database.
You can set a deletion flag for all PRT categories. For production resources/tools with a PRT master record (miscellaneous) however, this is only possible if the PRTs are no longer assigned to operations.
You can still display production resources/tools for which the deletion flag has been set. However, you can no longer change or reassign them. During archiving or in the next deletion program run these production resources/tools are deleted from the database, provided that they are no longer used.

At present, there is no archiving or deletion program for production resources/tools with a PRT master record.
You can remove a deletion flag at any time, as long as the production resource/tool has not been deleted from the database.
