You have to use in combination of below three.

SET NULLINTERPRET=;

SET NULLVALUE='Not Available';

NULLASVALUE *;

Hi,

Check this from Qlikview help file, this applicable for only Text, Excel or Inline statement

NullInterpret

The defined symbol will when it occurs in a text file, Excel file or an inline statement be interpreted as NULL. A user-defined variable.

Example:

set NullInterpret=' ';

set NullInterpret =;

will NOT return null values for blank values in Excel (but it will for a csv text file)

set NullInterpret ='';

will return null values for blank values in Excel (but will NOT for a csv text files)

Example:

set NullInterpret ='';

EMP:

LOAD EMPNO,ENAME,JOB,date(DATE) as DATE,Ceil(month(date(DATE))/3) as Quarter,SAL,

If(IsNull(SAL), 'NULL', 'NOT NULL') AS Status,

Alt(SAL,'NULL'&RecNo()) as SAL1 Inline [

In the above script empty values are interpreted as null values. If you remove that then it won't consider the empty values as null values.
