They create a Drawing with a Part or Assembly shown on it. This Drawing is stored into Windchill PDM Link and released in this combination. After a while they change something on the parts and store the parts only without updating the drawing. Now if somebody else receives the drawing out of Windchill (defauld Setting is "latest") he will get a version different to that version that was checked in and released before. It would be good to have a special status symbol inside the workspace (like the out of date clock) that make it transparent to the user that the current situation is not the as stored configuration of the current drawing.
