This tool allows building a report with side-by-side sub-reports. Use it to run a comparative analysis on the same page. It's helpful for reviewing multiple parameters, totals, and compare results at different time intervals. The Compare Period option is designed to create a report that shows two sub-reports side-by-side. You can view more info about it in the article Compare Period Mode in Summary and Orig-Term Reports.

To enable this option, click on the plus  icon next to the Period field and specify both intervals (Period 1/Period 2) for the report.
