Previewing a Report
At any time during the process of creating a report, you can refer to the Preview section at the bottom of the page, in order to view the final structure of the report to be created. However, the Preview will not be ready for viewing unless there is at least one table row defined.
Once finished with adding report components and structuring the report table structure, you can expand the Preview section to check whether the report created clearly communicates the information that needed to be gathered for analysis.
