2. Re: Live connecting ignores inner join
Leo Kaplun Mar 13, 2016 5:20 AM (in response to Tharashasank Davuluru)Thanks for that. I have done that, it's what Tableau recommends we do to create a date prameter.
But it's still seems weird that the Inner Join is ignored in this case.

This is intentional. It's done for performance reasons - it is usually much faster to get the domain of a dimension table if you don't also check that all the values are in the fact table. It's also useful in case data is added in the future.
Once you create an extract, everything is pre-joined so there's no need for this optimization.
