You can schedule refreshes after you publish on to a Tableau Server. Do you have a Tableau Server? Are you publishing to it in the first place?
Thank you for your reply. I tried to publish on the server But it takes quite long for the data to refresh. I wonder whether I should switch from LIVE to EXTRACT. Could you please explain the difference between them?
Thank you!! I am newbie on this. We do have Tableau Server.
Yes, you should switch to an extract. I will let you read this to understand more about live and extract.
After the data is extracted, you can then publish to the server and schedule refreshes on the server as required.
