The web console has a function-locking mechanism that prevents two users from accessing the Directory Management screen at the same time.
This means that when user A is arranging managed products using Directory Management, user B, who is also logged on to the web console, cannot access the Directory Management screen.
If you attempt to access a locked option, the locked option information screen appears. Control Manager only allows one user to use the function at a time.
To verify that the function is still in use, periodically click Reload.
To release the lock, click Break to release the lock.
The unlock function is available for users with the privileges to manage product folders.
