I'm not sure what you mean. Are you saying that you think you need a project in order to perform SCC operations? Is so, that is not the case. As long as PushOK is configured in LabVIEW appropriately, you can perforce SCC operations outside of a project. You should also be able to check out the file itself.
The only other complaint I have is that a project file is required to interact with the repository. I have my LV project files source controlled in the repository and must use an external tool to check out a working copy of the .proj file.
