Only the one that you have selected will change to Live. This can be handy if you want to have some data sources use live connections and other data sources use extracts.
Thanks a lot Jeffery. That Helps.
Other thing is that when i am changing to live connection, then some calculated filed are getting invalid.
I have renamed the Dimension names in the data pane window in Tableau. Do you have any idea if this is the reason for calculation invalid?
Do you know why the calculated fields are invalid?
If you open the invalid calculations and click the red "The calculation contains errors" icon, it'll give you more information. If you reply with that info, we can help diagnose your problem!
