The Scheduled Exports Screen is part of the Administrator Settings..  This allows the logs of exports to be viewed and checked.

It is possible to search for a specific Dashboard or visualisation, or alternatively a Tree-view of categories and Dashboards/Visualisations are displayed. The first group of "Scheduled Exports" show objects that are currently Scheduled, "Unscheduled Exports" are for objects that have previously been scheduled.

When a Dashboard/Visualisation display object is selected the details of the object, its next Scheduled time and history of the Scheduled exports are displayed.
