Repository Object Locks and Versions
Effective in version 10.0, if you try to edit an object that another user has locked, you receive a notification that the object is locked by another user. You can choose to review the object in read-only mode, or you can save the object with another name.
Previously, more than one user was allowed to open and edit an object. Only the last user who tried to save the object received a notification that the object had been changed by another user.
If the Model repository is integrated with a version control system, you must check out an object before you edit it.
