How to create a flag for not existing dataset in k… – Qlik Community

Hi,

First of all, I am new to the Community, so please excuse if my question isn’t appropriate in any way.

 

I am loading two table like this:

 

A:

load

main_key,

sub_key

resident xyz;

 

B:

left keep (A)

load sub_key

resident abc;

 

Now I want a flag in table A which shows if a corresponding value is existing in table B or not.

 

Thank you very much for your support.
