Let's discuss the proverbial elephant in the room. If I understand this correctly, it is currently impossible to publish live data to Server using Tableau Prep Tableau Prep - Live Data The only recommendation made in the forum is to use a custom SQL query in Desktop. Let's just say that my experience with using custom SQL queries has not made me a happy camper. They are almost always prone to snags, gotchas, errors, and generally bad data. The whole reason for using Tableau Prep in the first place is to veer as far away from custom SQL queries as much as possible. So why hasn't Tableau Prep made it possible to publish live data to an internal server? Maybe someone reading this will have an excellent answer, or maybe a better one than what I have seen thus far.
