We started using Windchill, Since 2012 from there Data's in Windchill are scattered and no proper life cycle states where followed.
So we decided to cleanup the unused objects from Windchill. We purged to cleanup the data created from 2012, 2013, 2014, 2015 & 2016 with below criteria's in manage queries.
Object Type : EPM Document
Version at Maturity : Design Released
Version at Maturity : Preliminary Released
Iteration (All but last) : 2
Created : 01-01-2012 to 31-12-2012
Modified : 01-01-2012 to 31-12-2012
Created Purge Job for the above query criteria and previewed the same before submitting the purge job.
For Example: The preview shows with result 2300 objects eligible for purge which includes family table (Instance and Generic) as well. But we were able to purge 20% from the eligible object rest all are family table objects.
> Data growth per year 2TB
> Reduce the data growth by purging the unused data's
> Reduce the drive size
Is there any way to purge the family table (Instance and Generic)
