Having example data described in parent_child_01.png (attached to this thread). I'd like to display this data ina parent/child way. Check parent_child_02.png, there are a subset of fields from the example data grouped on fields ProjektNr and Aktivitet. When clicking the + sign I'd like to expand the rest of the data belonging to current ProjektNr and Aktivitet like in parent_child_03.png.
How do I accomplish this. Been tryin around without success. Should I use a table, a crosstab, subreports??
