Report templates define how the data of a report is rendered. For detailed information about managing your report templates, see Managing Report Templates.
Because shared global reports are available in all projects for all users, user roles that are able to update and delete them require special permissions: Manage shared global reports and Delete shared global reports. These permissions also apply to report templates that are used in shared global reports. Non-shared global reports and report templates can be updated and deleted by user roles with the standard report permissions for updating and deleting reports.
