A public group provides the cleanest reusable security boundary for report and dashboard folder access. UC can create a Sales Managers public group and maintain the appropriate managers as members, then grant that group the required folder access. Folder sharing remains attached to the group instead of being maintained user by user, which removes the recurring monthly administration described in the scenario. Enhanced folder sharing supports audiences such as users, roles, territories, and public groups, with the folder access level determining whether members can view, edit, or manage the content. Profiles are not the normal sharing target for public report and dashboard folders, so changing a profile does not solve the folder-membership problem. The role hierarchy also should not be treated as though folder access automatically rolls upward in the same way as record access. Folder security is a separate authorization layer. Public groups are particularly effective when a functional population must receive identical access even though membership changes over time.
