We are just getting started with the direct connection to Salesforce.com and its great but we find the joining capabilities to be cumbersome.
Has anyone thought about using Salesforce reports as a data source instead of querying tables directly or allowing for the ability to write SOQL queries.
I think this would make creating data sets (and applying filters) a little simpler.
Did you get any solution to the above problem? I am trying to do the same, and it doesn't seem feasible, nor Tableau allows to use SOQL with Salesforce connector.
And obviously downloading whole data limits the operational speed.
