Hello,You can use a case construct to compare two null values in
filtering conditionsFor example I am comparing first name and last name
on equal operatorCase(When(Lower(@firstName) IS NULL , 'Null') ,
Else(Lower(@firstName))) = Case(When(Lower(@lastName) IS NULL , 'Null')
, Else(Lower(@lastName)))Above condition will return recipient records
where firstname is equal to lastname or both firstname and lastname are
null
