If you are using Tableau Server, that is if the dashboard is published to Tableau Server, you can use User Functions that include USERNAME and FULLNAME to represent the person logged into Tableau Server. This is a function you can add to a calculated field, which you can then use in any view and URL actions.
Hope that helps!
thks a lot for your answer.
So, if i undertand well: i create my empty dashboard, i create my calculated field to retrieve user info that i use in my url action.
it sounds good?
Almost! You'll create the calculated field on an empty sheet (on the dimensions shelf), then you'll have to add the calculated field to the sheet itself (make part of the view). You can later add the sheet to your dashboard, but this is optional.
Whether it's a sheet or a dashboard, you can then use the calculated field on a URL Action.
Thks a lot Santiago.
So, today in my url i use: "user <my_url>/user=<name>", where <name> is a calculated field that contains the FULLNAME.
Last question is: exists a way to hide the value for the user? For security reason i would like to avoid to have the name in clear in the url: if i know some user_name i can directly access with theyr login??
