Several reportings variants exist for routings. Let's get an overview.
Where-Used Lists

You can generate where-used lists to display the routings that use particular work centers, capacities, reference operation sets, reference rate routings, and PRTs. You may need this information if you want to delete a work center or reference operation set after checking whether the system is using it in a routing. You can also display routings that have been deleted online, but exist in the database.
Mass Change and Reporting
You are able to do mass changes to work centers, PRTS of reference operation sets.
The system generates a list of all the routings that use the object to be replaced.
When you use the mass replacement function without a change number, the new objects will have the same validity periods as the old objects.
