I need to do union of two different data sources, MS Sql Server and an Excel file, Is there any way can we do this from Tableau Desktop? I am using 2020.3

Hello @lalitha p ,
It is not possible to union from different types of datasources. You can either use Tableau prep, or a solution like the one on this thread.

Hope this helps!
