joined multiple data connections and wish to filter or hide the null values in the data source ... I did all the steps but his outcome doesn't show null values and mine does?!

Hi, PLease be aware that Tableau updated their version of the software and this is the reason why there are some differences in the way data is displayed. If you see too many null values you can scroll down and should be able to notice that there are also non-null values. Best, Ned
