is there way to have the "nested" sub-totals too? When I added 2 groupings, it is acting as a single grouping by group-1, group-2, effectively one group based on 2 data-fields. I want
Group-1 : header
Group-2 ...and so on.
if I add 2 groups, they become 2 non-nested sibling groups.
Can someone elaborate how nested subgroups are done?
