Locking and Unlocking Objects

You can lock objects to prevent other users from modifying them. Then, you can unlock them to allow modifications by other users.

You can either lock the object (the reference), the usage of this object in the structure (the instance), or both.

For more information, see About Locks.

  1. Select one or several objects.
  2. From the Collaboration section of the action bar, click Lock or Unlock .

    Tip: You can also click the lock status of the object.

    The Lock or Unlock dialog box appears.
  3. To lock or unlock the object, select the Reference option. To lock or unlock the usage of the object in the structure, select the Instance option.

    Notes:
    • These options might not be displayed depending on the app and the object type. In that case, the object is locked.
    • The Instance or Reference option might be initially selected based on your previous selection.
    • When you select an aggregated representation, it is locked/unlocked as requested, regardless of the option you select.

  4. Click OK.

The object is locked or unlocked, and the lock status of the reference is updated (if modified).

Important: An error message appears if:
  • You try to lock an object that is opened by another user at the same time, and that has already been modified by this other user.
  • The object you selected contains multiple objects, and one or several are locked by another user.
