Are you using an extract? An extract won't be refreshed by merely refreshing the browser window. You'd need to schedule a refresh of the extract.
If that's not the issue, I might need some more info:
1. What happens if you use the workbook's refresh button?
Simply refreshing the browser might still result in cached data from the Data Server component of Tableau Server -- but hitting the refresh button should get fresh data if it's available.
2. What are you expecting? Has the source data changed and you are expecting to see a different visualization?
Thanks for replying,
Answers to your questions,
No we are not using extract, we are directly connecting to database and trying to get live data.
If we use workbook's refresh button then its fetching the data, No issues here.
My expectation is , even on browser refresh i should be able to fetch the live datajust like worksheet refresh button.
Do i need to do any setup in the server
