NullDisplay
The NullDisplay value is used to tell Qlik Sense how we want to show any value that is coming from the source that is null. A null value isn't a blank value, but a value that doesn't exist.
Whenever NullDisplay is set, the null value is replaced by the value set by the user.
The following is an example of how to use this variable:
SET NullDisplay = 'Null Value';
This variable works when pulling data with ODBC and connectors.
