Measures with USERELATIONSHIP and conditions (filters) causing matrix/table to display duplicates

[Anonymous]

Hi there,

I have a measure which uses USERELATIONSHIP in conjunction with some filter conditions which works fine until I put the measure into a matrix and make one of the rows in the matrix the same as one of the columns in one of the filters. For example, one of the measures I am using has a condition which excludes any rows where the value in the Lab column equals "SEROLOGY":

TAT % (All) = (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
'Mart vw_TestMeasures'[TAT Met]="Yes",
'Mart vw_TestMeasures'[Lab]<>"SEROLOGY",
'Mart vw_TestMeasures'[Count in TAT]="Yes"
))
/ (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
'Mart vw_TestMeasures'[Lab]<>"SEROLOGY",
'Mart vw_TestMeasures'[Count in TAT]="Yes"
))

However, when I create a matrix which uses this measure and includes Lab as a row, while it correctly removes any SEROLOGY values, I now get duplicate values for each column in the matrix. For example, what I get is this:

When what I expect to see is all different values, something like this:

Does anyone know how I could alter the DAX expression so that I don't get duplicates showing up in the matrix?

Thanks!

Hi @Anonymous,

I was recently faced with the same issue.

When you add the filter parameters to the calculate like that it is not taking into account any outside filter context for that column (clearing any filters on that column), you are essentially writing:

TAT % (All) = (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
FILTER(ALL([TAT Met]),'Mart vw_TestMeasures'[TAT Met]="Yes"),
FILTER(ALL([Lab]),'Mart vw_TestMeasures'[Lab]<>"SEROLOGY"),
FILTER(ALL([Count in TAT]),'Mart vw_TestMeasures'[Count in TAT]="Yes")
))
/ (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
FILTER(ALL([Lab]),'Mart vw_TestMeasures'[Lab]<>"SEROLOGY",)
FILTER(ALL([Count in TAT]),'Mart vw_TestMeasures'[Count in TAT]="Yes")
))

What worked for me is using the KEEPFILTERS function to make sure that it only adds to existing filters, Try this code:

TAT % (All) = (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
KEEPFILTERS('Mart vw_TestMeasures'[TAT Met]="Yes"),
KEEPFILTERS('Mart vw_TestMeasures'[Lab]<>"SEROLOGY"),
KEEPFILTERS('Mart vw_TestMeasures'[Count in TAT]="Yes")
))
/ (CALCULATE(
COUNTROWS('Mart vw_TestMeasures'), 
USERELATIONSHIP('Mart vw_DimDate'[Date],'Mart vw_TestMeasures'[Client Due Date]),
KEEPFILTERS('Mart vw_TestMeasures'[Lab]<>"SEROLOGY"),
KEEPFILTERS('Mart vw_TestMeasures'[Count in TAT]="Yes")
))

Also use DIVIDE function instead of / arithmetic

Hope that can help anyone else too

Thanks,

Jake

Hi @Anonymous,

Could you try the formula below to see if it works in your scenario? 

TAT % (All) =
IF (
    FIRSTNONBLANK ( 'Mart vw_TestMeasures', 1 ),
    BLANK (),
    DIVIDE (
        CALCULATE (
            COUNTROWS ( 'Mart vw_TestMeasures' ),
            USERELATIONSHIP ( 'Mart vw_DimDate'[Date], 'Mart vw_TestMeasures'[Client Due Date] ),
            'Mart vw_TestMeasures'[TAT Met] = "Yes",
            'Mart vw_TestMeasures'[Count in TAT] = "Yes"
        ),
        CALCULATE (
            COUNTROWS ( 'Mart vw_TestMeasures' ),
            USERELATIONSHIP ( 'Mart vw_DimDate'[Date], 'Mart vw_TestMeasures'[Client Due Date] ),
            'Mart vw_TestMeasures'[Count in TAT] = "Yes"
        )
    )
)
