How complete empty values of a certain table?

[benoittanga]

Hi all ,

I have a question regarding "Null" values of one my table in QV. I'll try to explain as better as I can:

- My QV is charging a lot tables, and most of them contain empty values
- the main role of my app is to calculate KPI (completeness, accuracy) and so I have configure the NullInterpret in the beginning of my script, with these statements :

// AUTOMATIC CONVERT OF NULL INTO 'VIDE'
MissingTextMap:
MAPPING LOAD
null(), 'VIDE' AutoGenerate 1;

// AUTOMATIC CONVERT OF NULL INTO 'VIDE' WORD + ZERO NUMBER
MissingNumberMap:
MAPPING LOAD
null(), Dual('VIDE',0) AutoGenerate 1;

// HIDE PREFIX
Set hideprefix = '_';
set NullInterpret='';

My problem is: one of my table is storing results of a calculation, with the value "OK" (when the calculation is correct, obvously). I need to fill the others values by the word "NOK" but I don't know how to do it.

Theses "Null" Values are not filled with the word "VIDE" (as the others table) and so I don't really understand what is going on

Waiting for your feedback, and thanks for having read me

Let's say that column which contain OK is "Flag"

You do the Following in the script 

if(len(trim(Flag))=0,'NOK',Flag) as Flag

You don't show your MAP USING statement, that would be required. Also, if your null values are created indirectly by a join, you may have to pass through the table again to map.  See https://qlikviewcookbook.com/2013/01/filling-default-values-using-mapping/
