The Windchill Scheduler is an internal service used by different Windchill services to schedule execution of certain tasks. Tasks can be run once or periodically, and can be scheduled for a particular time or immediately after the scheduling takes place. Typical scheduled tasks involve external vaulting and content replication.

Scheduled tasks are executed using the Windchill queue service, which allows the inheritance of the advantages of the background processing. For instance, if the background method server is used, scheduled tasks will be running in it.

The Windchill Scheduler service keeps the log of each executed task in history objects that contain the current and historical status information. For example, if you are scheduling revaulting and you select schedule items and click Log, history objects supply the data that appears in the Revaulting History window.
