Here is a representation of a notification parent/child relationship. Sam, the Safety Manager of ABC Trucking, needs to receive all Critical Event Report (CER) email alerts for vehicles in global groups Region 1, Region 2, and Region 3.
A parent group called "CER Alerts" is created with Sam as the user and these groups as the child groups. In CER Notifications, Sam's email address is used to create a notification with "CER Alerts" as the group selection.
