Have you add Permissions for The Tableau Server in The Shared Drive so that it can have access to your files.
Thanks for the reply!
Can you please let me know the steps to add the permissions for tableau server to the shared drive.
Neeru, the service account that runs Tableau Server needs to be in an Active Directory group that has rights to read that folder. Assuming you're in a Windows environment, of course.
Work with your network security or Active Directory team to add the Tableau Service Account to the appropriate AD group.
