Dundas BI offers many different types of filter controls to accommodate specific designs and user experiences one may want to create in their dashboards. These include controls such as member filter (drop-down list), date calendars, sliders, cascading filters, numeric filters and more specialized types of filters such as level, offset and dynamic filters.
One quick way to setup common filters on your dashboards is to use the smart filter under the filters menu. The smart filter will scan your dashboard metric sets and find an appropriate filter control (i.e. member filter for hierarchy, date filter for date dimension or numeric filter for measures) and will then connect the newly added filter to all of the similar elements on the same dashboard.
Essentially, it allows you to add a filter that can be applied to your entire dashboard with a single click!
