Use Filters in Overview Dashboards

In the Overview Dashboards, you can create the filters that are meant to be seen and used by end users as Dashboard Filters.

The Overview Dashboards use Workbook Filters (seen in the top Filter Bar) behind the scenes.

To simplify consumption of business content, you can hide the Workbook Filters by turning the Filter Bar off in the Present Mode for the end user.

The Dashboard Filters may use their default behavior to show the values of the subject area column or may be populated by parameters.
