Set Analysis Exclusion question

[jduluc12]

Hi,

My data set looks like this.

[a]:
LOAD * INLINE [
ID, Type
1, S
2, S
3, C
4, S
5, S
6, C
22, S
];

NoConcatenate
[b]:
LOAD * INLINE [
ID, SNN
1, AAA
2, BBB
3, AAA
4, FFF
5, GGG
6, FFF
22, III
];

I want to find all SNN which are connected to Type 'S' but not with Type 'C'. 

In this data set, there are 3 such SNN.

• BBB
• GGG
• III 

I am writing an exclusion set analysis.

=Concat({<Type={'S'}> -  <Type={'C'}>}SNN, ',') 

and it returns all SNNs.

AAA, BBB, FFF, GGG, III.

What am I doing wrong here?

Hi,

Your formula is an equivalent to filter rows in the table "a" and then looking for corresponding values in the table "b" (so all SNN values linked to Type 'S').

To achieve what you want, I suggest to filter directly on the SNN field, using P() function (see https://help.qlik.com/en-US/sense/September2019/Subsystems/Hub/Content/Sense_Hub/ChartFunctions/SetA...) :

=Concat({$<[SNN] = P({$<[Type] = {"S"}>} [SNN])-P({$<[Type] = {"C"}>} [SNN])>} [SNN], ',')

Hope this helps you.

Best regards,

Nicolas

This also worked

=Concat({<SNN=E({<Type={'C'}>})>}SNN, ',')
