I'm a relatively new user, and our team is exploring to see if there is a way we can limit our filters, or create an error msg when a filters drills down below 5 cases. Displaying Demographic on data on less than 5 subjects in a specific view may jeopardize anonymity. Any suggestion are welcome.
Yes, it's definitely possible but it entirely depends on the structure of your data and the types of metrics you are running.
You could effectively do some conditional logic based around IF COUNT([thing]) > 5 THEN do something ... in a filter or calculated field.
