      <p class="para_division">When you specify All, the software checks all group objects in the work part. If a group object has no members, it deletes it. If a group object contains members, the software examines them to see if one of them represents the group itself (a self-referencing group). If the system finds a self-referencing link, it breaks it. If breaking such a link causes a group to have no members, it deletes that group.</p>
