When a report result is created under a report definition, the report result is in unread state. An unread report result appears with a blue dot next to the report result in the Report Viewer. When you view a report result, the blue dot is removed to indicate that the report has been read. You can also manually mark a report result as read or unread without viewing it by using the options in the drop-down list.
In the Report Viewer, each of the report templates or definitions shows the number of unread reports next to it.
NOTE:The reports marked as read or unread are on a per-user basis. Each user can have a different set of read or unread reports.
