USERELATIONSHIP needs selection to trigger correct calculation of measure? What am I missing?


This might be a stupid question, but I seem to have a general misunderstanding when using Measures, Filters and the DAX USERELATIONSHIP function.

I seems to work just fine for my dataset, but I always need to make a selection thus filter the data for which it then evaluates the measure using USERELATIONSHIP correctly. If I unselect everything it seems to ignore the USERELATIONSHIP calculation and gives the results without it.


I just have 2 tables with an inactive relationship:


My measure is showing distinct values as such:


distinct 2s also in 1 =
DISTINCTCOUNT('Table (2)'[number 2]) ,
'Table'[number 1],
'Table (2)'[number 2]
My expected outcome here would be 2, yet it shows as 3. 
It is counting the number 2 value '9' which is not in Table 1.


If I make a selection in the number 1 table it shows the values correctly as only '1'


How can I get the result of '2' for my measure posted above that works without a selection?

I uploaded a very simple pbix file to show what I mean.

Thanks for your help.

Hi @systemic_till ,

You can add write measure to calculate table2 records with if statement to compare current row contents with tbale1 records:

Measure =
IF (
    SELECTEDVALUE ( 'Table (2)'[number 2] ) IN VALUES ( 'Table'[number 1] ),
        COUNT ( 'Table (2)'[number 2] ),
        USERELATIONSHIP ( 'Table'[number 1], 'Table (2)'[number 2] )


If above not help, please explain your requirement more clarify with the expected result.

Hi @v-pn ,
Thanks for you answer.
It didn't clarify my issue though.

In my setup, everything works as expected, if I make a selection.
Only when nothing is selected I am getting confusing results.

My expected result is 2, when nothing is selected.
Yet, I get a result of 3 as if the USERELATIONSHIP filter was missing entirely.

So, to clarify:

// Measure 1

no relationship = CALCULATE (DISTINCTCOUNT('Table (2)'[number 2])   
==> that gives 3. That's ok.

//Measure 2
distinct 2s also in 1 =

CALCULATE (DISTINCTCOUNT('Table (2)'[number 2]) ,
'Table'[number 1],
'Table (2)'[number 2]

==> that also gives 3 when no selection is made. Why is it not 2?
