I have used Publish to Tableau Server macro for over a years. It works fine when I want to overwrite the data.
However, the current macros (from Alteryx Gallery and Invisio) won't work with appending the data. Please modify or develop a workable macro for 'Append the data to Tableau Server'. It will save a lot of time in the daily update process.
Note: I am using Alteryx 11 and Tableau 10.1. Thank you very much.
