dax in drilldown works without relationship

[animebuff]

i have write a simple dax of subtraction and division and I have a region as drilldown

my requirement says to remove the relationship between dim country table and fact table so I removed it using CROSSFILTER 

since I remove the relationship my values for individual region is not right, all region inside a month year shows same value

ex. if month year nov 24 total is 200 

nov 24 asia is 100

nov 24 europe is 25

nov 24 NA is 50

nov 24 LA is 25

after removing the relationship using CROSSFILTER
in drilldown for all region ( asia, europe, NA and LA ), I get 200 

my requirement is to remove country region relationship at the same time the overall dax logic should work on drilldown

[animebuff]

Requirement:

left side visual is what by default we get in PBI
what I need is right side visual but the values of all region should not be 0.31 rather
apac - 1

europe - 0.5

la - 0.5

afracia - 1

australia - 1

na - 1

uae - 0

only apac, europe and la have both numerator and denominator so it should give respective values

uae only has denominator so it is 0 (0/anything)

rest regions doesn't have data so it should give value as 1

-----------------------------------------------------------------------------------------------------------------------

dax:

default dax = CALCULATE(COUNT('S rate'[success]),'S rate'[inclusion flag]="Y")/COUNT('S rate'[success])

modified dax = CALCULATE(CALCULATE(COUNT('S rate'[success]),'S rate'[inclusion flag]="Y")/COUNT('S rate'[success]),CROSSFILTER(region[region],'S rate'[region],None))

Hi @animebuff ,Thank you for reaching out to Microsoft Fabric Community Forum.

If the direct relationship between the dimCountry table and the fact table is removed, it will impact the filtering context, so now you see the same total for all regions.

We can use the TREATAS function to create a virtual relationship between the dimCountry table and the fact table. This way, we can eliminate the physical relationship while keeping the correct context for the calculations.

Sample Data:

dimCountry Table

fact Table

Total Value Measure:

Total Value =

VAR SelectedCountries = VALUES(dimCountry[Country])

RETURN

CALCULATE (

    SUM(fact[Value]),

    TREATAS(SelectedCountries, fact[Country])

)

Set up a Matrix Visual:

Updated DAX Measure

Measure = 
VAR CurrentRegionFilter = 
VALUES(DimCountry[Region]) 
RETURN
CALCULATE(
SUM(FactTable[Sales]), 
TREATAS(CurrentRegionFilter, FactTable[Region]) 
)
