My question is: Is there a possibility to do the same without entering specific field name? I mean, a default handeling for those kind of null-values. My qlik application has many fields and I don't want to check them all for null-values.
A comma separated list of the fields for which NullAsValue should be turned on. Using * as field list indicates all fields. The wildcard characters * and ? are allowed in field names. Quoting of field names may be necessary when wildcards are used.
