I have tried to solve this with bridge tables, with snowflakes and I don't know how many different versions, but I still can't get it work. When fact has multiple rows for the lowest dimension level values (as it always will), OBIEE multiplies the data. My data model looks like this:

How should I model that N:N between user and group AND get the right data out from my fact? This works fine as long as I don't add the group anyway. And pls do not link any documentation, blogs or such unless it describes exactly this situation - I have checked them already and they didn't help. I need now step-by-step plan to sort this out.
