Unable to generate default report "Project Tasks"

Hi all,

I am working on Reports in Windchill 10.1. I am not able to generate(meaning -no values are retrieved) the default report "Project Tasks".

I am trying to retrieve the Days Overdue for a task attribute in particular. I have even tried making a custom report,but still the days overdue are not being retrieved.

Kindly help.

Any suggestions will be helpful

Thanks and regards,

Shweta Joshi
