we have published a data source to tableau server then we are trying to perform run now for full refresh and incremental refresh but no success.
Error is "Access denied for user 'root'@'serverxxx' (using password:NO) Invalid username and password."
Please refer to the attachment to see the error message provided by the Background Tasks in Server Analysis.
Have you tried editing the data connection for this workbook on the server and changing/supplying the username/password?
Basically, you can edit the connection properties by clicking "Modify" link in Data Connections page but not for published data sources.
Thanks.
Strange, I can do it for published data source by selecting the connection in Administration - Data Connections and clicking Edit link. Are you logged in to Tableau Server with admin privileges? What version of Server are you using?
Yes, I believe that I am using admin privileged user named 'root'
