    Filter DATA source (keep only the first sub-category for each category)

    axel Bl

      Hello everyone,


      I'm new to Tableau and I want to know if there is a way to filter my data source so I can keep only the first sub-category for each category (the categories changes every month so the filter shouldn't be fixed on values..).

      And Then extract the CSV file which will be used as a source file for another Tableau dachboard.


      I know this should be done using an ETL software but I have only Tableau to do it.

      Can Tableau prep do this type of job?
