## Set analysis - Count with dynamic condition

Hello everyone,

I'm a beginner on Qlik Sense, and I'm stuck with the issue described below, I need to understand.

Let me explain my issue: I'm working on QS to generate reports about SonarQube analysis. We have several projects that are frequently analyzed, and for each project we store issues. I want to count a specific kind of issue ([TAG_ID-ID]=70) for the last analysis ([SNAPSHOT_ID-ID] = LAST_ANALYSIS_ID) by not decommissionned projects (DECOMMISSIONED=0).

So I wrote this formula:
FORMULA 1 : sum(if(DECOMMISSIONED=0,Aggr(Count(if([SNAPSHOT_ID-ID] = LAST_ANALYSIS_ID AND [TAG_ID-ID]=70,1)),FULL_NAME)))

This formula works, but now I would like not get the lastest analysis M per project, but have a slicer related to variable N to pick up the M-N last analysis (so a dynamic count depending on the N variable)

And therefore I modify my formula like that :

FORMULA 2 : sum(if(DECOMMISSIONED=0,Aggr(Count(if([SNAPSHOT_ID-ID] = FirstSortedValue([SNAPSHOT_ID-ID],-DATE,N) AND [TAG_ID-ID]=70,1)),FULL_NAME)))

This formula doesn't work, even replacing N by 1 (should have the same result).
Yet the only difference is in the first case I use LAST_ANALYSIS_ID calculed in the load script, and in the second one I use the function  FirstSortedValue().

Below a picture to illustrate my issue :

First column: Project Name (FULL_NAME field)
2nd column: PARAM 1 - LAST_ANALYSIS_ID filed calculated in the load script as Max([SNAPSHOT_ID-ID]) group by FULL_NAME
3rd column: PARAM 2 - LAST_ANALYSIS_ID calculated with the FirstSortedValue(), same value than PARAM 1
4th column: count using PARAM 1 - it works
5th column: count using PARAM 2 - it doesn't work

Why the FORMULA 2 in the 5th column is not working and how to make it works ? ( still in order to create a dynamic count with the slicer created)

I'm going to build it because I can't share my qvf as it's based on company data.

I'll post it here as soon as I manage to reproduce the same behavior.

It would be difficult to know the issue without seeing it, but in general the problem with the expression which uses the firstsortedvalue instead of the field is that it is using FirstSortedValue within Count.... you are not allowed to do things like

Sum(Count(Measure))... you need to use Aggr... Sum(Aggr(Count(Measure), SomeDimension/s))

I come back with a QVF file, where you can find the same structure than before.

I draw too charts :

- a table as before

- a pivot table where projects are group by programs (the final purpose)

And I created a slider on the N variable, but it seems not working so I haven't use it for now.

I could attach you also the excel file from which I loaded datas if you need it.

Try this

``Count(DISTINCT {<[TAG_ID-ID] = {70}, DECOMMISSIONED = {0}>} If([DATE] = Aggr(NODISTINCT Max(DATE, N), FULL_NAME, PROGRAM), [ISSUES_ID-ID]))``

Great job, it works ! Thanks a lot 🙂

Just for my mind, I don't understand why you used NODISTINCT aggr rather than DISTINCT in your second part.
Basicaly, I would choose DISTINCT but it seems not be the good choice)
