Outer joins are in preview now but only to be supported at the modeling level, we need them supported at the dashboard level.
For customers who's clients require self service capabilities, and do not have the ability to modify data models, this is critical functionality. In this case, not having this functionality will stunt the adoption and roll out of Sisense all together until addressed.
Inner joins, at the dashboard level does not meet requirements, and is detrimental to the value of the solution overall. This is a huge blocker for rolling out Sisense to our customers.
