As you generate reports and drill down on rows to generate detailed sub reports, the number of pages in the Reporting window will grow. You can move about from page to page simply by clicking on the page name.
You can also return to the Selection page and change your selection criteria to start all over again with a newly generated report at any time. If you change your selection criteria and generate a new report, all subsequent or dependent page (i.e., drill down and chart tabs) are closed.
To close a page, right click on the page folder top and select Close from the pop-up menu.
