Tableau IN operator is a logical function used to test whether a specified value matches any value in a list of comma-separated values, a set, or combined fields.
(Note: The IN operator supports string, date, numeric and Boolean data types)
IN Syntax
<expr1> IN <expr2>
Where the value of <expr1> can be a set, list on values or combined fields.
Example 1
SUM([Sales]) in (2,297,202, 2,340,789, 3,456,782)
This expression returns TRUE if SUM([Sales]) matches any value in the comma-separated values
Example 2
(This calculation returns ‘Eastern Africa’ for each country matching the comma-separated values)
