How to: Create a Drilldown Report
A drill down report allows you to view your data by starting with a general category and moving through the hierarchy. Follow the instructions below to create your own tabular report.
Firstly, Create a new profile (refer to Editing a Tabular Report Profile )
There are two ways you can set up your drill down report on an existing profile:
First Option: drag the column header you want to group by to the top of the tabular report (See screenshot below). Then your report is already in a drill down format.
Open side bar.
There is a section called Grouping where you can press Add to add a new layer to your drill down report.
