You have the following dataset.
You plan to create a dashboard that will be filtered to show only data that is relevant to a specific Tableau user based on the Tableau_User_Name field.
You need to create a boolean calculated field to place on the data source filter.
Which formula should you use for the filter?
To create a boolean calculated field that filters the dataset based on the Tableau_User_Name field, you need a formula that directly compares the current Tableau user's username with the Tableau_User_Name field in the dataset. The expression USERNAME() = [Tableau_User_Name] accomplishes this comparison by checking if the username of the person currently logged into Tableau matches the Tableau_User_Name field in the dataset. If they match, the result is TRUE, and the data relevant to that user will be shown on the dashboard.
Answer is correct!
The answer is A, because it's boolean result https://help.tableau.com/current/pro/desktop/fr-fr/functions_functions_user.htm
C is the correct answer.
C is the correct answer.
It's C because isfullname() fuction can't use feild
oops, feild -> field
Returns TRUEwhether the person currently using Tableau is a member of a group matching the given string. Returns FALSEif they are not a member, and NULLif they are not logged in.
C. USERNAME()=[Tableau_User_Name]
It says in the question that we need to create a boolean calculated field. ANSWER **A**
Sorry, it is C
It is the correct answer since it will return Boolean value
It is C (it is not A because the ISFULLNAME() argument is a text and can't be a field).
Most be C. This is because A is comparing a boolean against a string with the = operator, the ISFULLNAME function can't accept fields. B is comparing name field with tableau_user_name which doesn't make any sense. And D is comparing the Name with the USERNAME() function which returns the current username, which is an email address for tableau server and not the full name of the user.
This is the way we do it in our company
USERNAME() is a built-in Tableau function that returns the user's Tableau login name (usually their email or AD name, depending on setup). Comparing it to [Tableau_User_Name] creates a boolean calculated field that’s TRUE only for rows belonging to the logged-in user. You can then drag this calculated field to the data source filter to restrict data at the source level.
