I have some questions.
Did you ever use PDMLink?
PDMlink works buy storing data in a workspace which is linked with commonspace(database). Certain data management tools are disabled in proe when using PDMLink. This is because renaming and deleting of objects can only be done in the workspace browser. Also your working directory is in fact the workspace. Does Enovia work this way?
I saw a small demo and was told that you only use Enovia if you want to actually checkin, otherwise it is as if you are saving in windows folders/directory structure.
