About Purging
Windchill allows you to permanently remove data (objects) from your production system using the purging method.
You use purge functionality to:
Specify selection criteria to identify data to be removed from the system
Remove unwanted data from the system, including both metadata and content
To purge data from the Windchill database, you specify object selection criteria for the purge job and then purge the data.
