Hello Von
one should nail down the exact context of "expiry date". When an author
creates a document, there are more than one dates managed in Windchill.
Date the document (meta data) is created
Date the file(Primary content) is uploaded.
Date the document is further updated.
Date the document is released.
If I am right, from the auditing purpose, the date the document is released
should be considered for expiry date.
If you dont want to over load the system with a timer robot, one can create
a schedule job (Windows/Unix) and check the lifecycle history for the
release date and notify the authors regarding the expiry information. The
schedule job can be executed once in a month for all the documents that will
expire during that month.
Hope this helps.
Thank you and have a great time.
