you can “drill down” into a report by clicking on one of the links in the table. This displays a detail view of the selected entity and the name of the entity appears in the navigation bar.
When a detail view appears, the entity type appears as in the title bar. You can change to a “Top / Bottom n” report of a different type, then click refresh to display a report of the top entities that apply to the current detailed entity. This process can continue until the conversation detail view is reached. This is the end of the line.
To return to the root view, for the drill-down, click the house icon in the upper left corner of the expanded portlet.
