Let me guess, you have a value (maybe a null) displaying in a Tableau filter and you want it to go away? You don’t want to leave it just sitting there because it’s ugly and your users are insatiably curious. You know if you leave it they are going to select it and you’re going to have to answer questions about what this “null” value means and why it’s a filter option.
You can leverage Tableau’s order of operations to your advantage. By using a set, you can remove the unwanted value(s) one step before dimension filters so your user never sees it as an option! Be careful though, once that value is removed from the worksheet, all associated data will be removed as well.
