I have the same issue. I don't believe it's really being used; it's just a wish and a hope. Its been talked about for too long
I don't know if anyone on this thread got an actual answer, but yes it is possible to connect PowerBI to Onestream. There are several different options and considerations based on the use case, which is probably why there's no 1 answer (there rarely is) on how to successfully achieve it. We have several different clients who we have helped do this, using different approaches so it really does "just depend". It also depends heavily on how much technical expertise someone has at the client as most typical finance users won't know how to do this in a productionized fashion with no errors/issues.
