"Security constraints prevent saving reports on table Upgrade Details - displaying report as read-only" Error message when trying to edit a report based on a system tableIssue Unable to edit a report that runs on a system table, for example, the "sys_upgrade_history_log" table. The following error message is displayed even for admin users:"Security constraints prevent saving reports on table Upgrade Details - displaying report as read-only"ReleaseAll ReleasesCauseBy default, system tables are not allowed for reports to be made on. No users including admins can create reports on these tables. If a report exists on any of these tables, it is probably that the system property "glide.ui.permitted_tables" was modified in the past for the specific instance, but currently, the property does not include those tables in the same instance. ResolutionTo fix the issue, add the system table to the system property "glide.ui.permitted_tables". This property contains a list of system tables (beginning with "sys_", comma separated), that are reportable. As it was mentioned previously, by default, system tables are not reportable.
