I had a few stumbles while setting up Windchill 11 M030 publishing on a test server. Specifically, I sent a couple of parts to the Publisher before I had the thumbnail worker online. Error is "No Thumbnail Created by Server", "WARNING" Unable to generate server thumbnail".
Now those parts have a viewable, but no thumbnail. I tried re-submitting them from the job monitor. This results in a "Representation Already Exists: default", followed by "end job".
Is there a way to either completely regenerate both the rep and the thumbnail OR just generate the missing thumbnails?
