How can I implement or Include Null values in Set Analysis in Qlik Sense

How can I implement this in Set Analysis? 

(cu.result ='' or cu.result = null) and tc.coursetype !=4

I have created a flag for null but can use it simultaneously for result=''

count({<SA Here>} id)
Thanks & Regards,

You may use something like this:

sign(len(trim(cu.result))) as NullFlag

and then within the expression:

count({< NullFlag = {0}>} id)

Load null as the value during script execution

NullAsValue result;
Set NullValue = 'NULL';

ABC:
Load
id,
If(id=2,Null(),result) as result,
coursetype;
load * Inline [
id, result,coursetype
1,,12
2,,13
2,,4
1,,4
3,bncv,8
4,lkd,7
3,bnn,4

];

and try the below set analysis/expression

=count({< coursetype-={'4'}, result={'' , 'NULL'}>} id)

or 

you can use the below expression directly without declaring null as a value during script execution

=count({<coursetype-={'4'}>}if(result='' or isnull(result),id))
