Permissions and tabvisibility are two options that administrators can adjust to fully restrict access to records for certain users or profiles. Permissions determine what users can do with records, such as create, read, edit, delete, view all, or modify all. Tab visibilitydetermines whether users can see a specific object tab in their app launcher or navigation bar. By setting permissions and tab visibility to none or hidden for deal records for service users or profiles, administrators can prevent them from accessing dealrecords via search or other methods.
