Roles and Views
You can define user rights to access the report as well as report availability in certain application views in the Roles and views tab of the report detail view.
If the Resource roles list contains at least one role, the report will be available only to users with this role. If no role is specified, the report is available to everyone.
Keep in mind that in the report list view (the Reports→Reports menu item) all system reports are visible because this view is considered administrative.
The Views list allows you to specify, in which views the report will be available when invoking RunReportAction, RunListEntityReportAction, RunSingleEntityReportAction or ShowExecutionReportHistoryAction actions. If no view is specified, the report won’t be available from any application view.
