You can select the dashboard context in the
portal with one or more global filters. A global filter may be a prompt,
a drill-up or drill-down action, or a report that is based on drill-through
content. For example, you can add a prompt control to a portal page
to automatically pass the selection to all reports on the page. When
a prompt answer is changed, all related reports will refresh accordingly.
So, if you answer a country or region prompt with Brazil, all related
reports on the page will be filtered to show the data for Brazil.
When these techniques are used on a tabbed dashboard, the context
is passed to all corresponding sections of the dashboard. This functionality
allows for a single selection to drive a number of reports at once.
