Apparently, Windchill 9.1 only allows deleting of the latest version (revision & iteration) of a CAD Document.
Some older posts have indicated that the way to delete non-latest is to use purge.
That's like using a sledge hammer to drive a thumb tack.
Is there any other way to delete a single iteration?
What if I want to delete all revisions & itertations?
Do I have to delete them one at a time, starting with the latest?
This was trivial in Intralink 3.x.
I think deletion of earlier iterations are not possible in PDM Link when latest iteration is available.
There are API's where FROM and TO iteration can be given for deletion.
