Closing a parent case
If the relationships feature is enabled, then cases may have parent-child relationships. When a case is being closed, an alert notifies the agent if the case has child cases. Agents who have parent-child cascade closing rights can close all child cases simultaneously. Agents can choose to have the close case email notification sent to the employees who are associated with the child cases. An agent who does not have parent-child cascade closing rights must close all child cases individually before closing a parent case.
