Modifying an existing report, as opposed to creating an entirely new report, is a time-saving option if the report you need is similar to a report you’ve run previously. If the base module and most of the fields you need already exist in a report for your tenant, modifying it is as easy as copying the report, removing or adding fields, and rearranging the fields to reflect the order you want them to appear in the report output. Having most of the values already in place saves you a lot of setup time.
