Previewing a report
Reports are rendered in HTML and each is mapped to a certain path for viewing. While editing a report, you can also preview its output using Report Builder's preview feature.
While your report is opened, select the Preview tab. This tab can be selected from the bottom of the editor. To preview the report within a browser, click the URL provided at the top of the Preview tab.
While your report is opened, click the Preview button on the toolbar located at the top. A new tab will open with the report's preview.
You can also open a report preview from the Navigator. Right click a report, and then select "Open in Browser" or "Open in New Tab".
