Your site role created as publisher.
Thanks for responding Sankar.
I am trying to understand connection between license and site role.
When we buy the license in tableau they offered three categories like creator, explorer,viewer.
once we bought license then we can set user roles in server like server admin or site admin etc. We can also create users and set site level roles.
Tableau license model min 5 explorer and if you need to buy viewer then min 100 viewer license.
Refer site roles
don't confuse with license and roles.
When your admin login and see the role of server then it will show server admin in settings.
