i haved created a group drilldown in the data model view as you told. il works finly. but when i try to use it in app overview, il don't work as the group drilldown in qlikview 11. Yes i agree that these aren't same product. but for me it isn't exactly a group.
In qlikview 11, for exemple i have a group drilldown geo, so i have country , region and city in this group. And i create un straight table an then i use my group Geo et create a new mesure count(pointsale).
if i select a country(on simple clic) , so i descend to a lower level et get my liste of region (region attached to my country selected).
but i can't get the same thing in sense if i select a county in ma table as i do in qlik 11, i can't get my liste of region for exemple. it seem that i should add these three fields in my sheet, if i select one value in my liste city, so my group change automaticly to level city. Perheps i don't konw how do it work.
