The Model repository does not lock the object when you open it. The Model repository locks the object only after you begin to edit it. For example, the Model repository locks a mapping when you insert a cursor in an editable field or connect mapping objects.

You can use more than one client tool to develop an object. For example, you can edit an object on one machine and then open the object on another machine and continue to edit it. When you return to the first machine, you must close the object editor and reopen it to regain the lock. The same principle applies when a user with administrative privileges unlocks an object that you had open.

For example, UserA can open and begin to edit an SQL data service, and then UserB can open and begin to edit the same object. If UserB saves and closes the object before UserA, the Model repository does not tell UserA of the potential conflict until UserA saves the object. In this case, UserA can save changes by saving the SQL data service with another name.
