Set analysis expression in pivot table

Hi,

I have been trying for some time now to show the number of lost customers in a pivot table by category and class using a set analysis expression. 

 

My expression looks like this: 

=Count({$<CustomerID=P({$<YEAR={'2018'}>})-P({$<YEAR={'2019'}>})>} Distinct CustomerID)

 

I am then displaying the numbers in the following table: 

 Cat1Cat2
Class1  
Class2  

 

My expression gives the wrong values for cat1 and cat2. However, when I choose only one of the categories using a filter pane it comes out right. Why does not my expression filter by cat1 and cat2 directely in the table?

Hi,

Can you share the sample data. with expected result.

Set analysis is not going to work because it is working at a chart level... try this using Aggr()

 

=Count(Aggr(
  If(Count(DISTINCT {<YEAR = {'2018'}>} CustomerID) = Count(DISTINCT {<YEAR = {'2019'}>} CustomerID)
    , CustomerID
  )
, CustomerID, Category))

Thanks @sunny_talwar Sunny. I am unfortunately getting an error  when trying to use your measure. For me it looked like Aggr was to be placed one parenthesis further up, but I can't get it to work then either. 

 

My data is too sensitive to be shared @nisha_rai , but thanks for wanting to help 🙂

Can you share the image of the expression with it's error message?
