Notes
Groups may perform tasks such as approving change requests, resolving incidents, receiving email notifications, or performing work order tasks. Any business rules, assignment rules, system roles, or attributes that refer to the group apply to all group members automatically. Users with the user_admin role can create and edit groups.
When possible, simplify user administration by assigning roles to groups. Create groups that contain all the roles necessary for specific personas, and then assign users to those groups.
Note: You can view group members by navigating to . Select a group name and view the members in theGroup Members related list.
Group records are stored in the Groups [sys_user_group] table.
