Except with dynamic filter is not working

i am trying to get all students from my table 1 that do not exist in table 2 using EXCEPT function. I was able to get it work when filters were hardcoded but as soon as i added dynamic filter, results show me blank. Not sure why this is happening. I am attaching the measure that is working and not working respectively (i have cohort and enrollment terms as two different slicers)

Measure :=
VAR selectedCohortTerm =
SELECTEDVALUE ( 'Dim Cohort Term'[Term Description] )
VAR selectedTrackingTerm =
SELECTEDVALUE ( 'Dim Enroll Term'[Term Description] )
VAR ADM =
CALCULATETABLE (
DISTINCT ( 'Fact Admissions'[Dim Person Key] ),
'Dim Cohort Term'[Term Description] = selectedCohortTerm
)
VAR ENRL =
CALCULATETABLE (
DISTINCT ( 'Fact eNROLLMENT'[Dim Person Key] ),
'Dim Enroll Term'[Term Description] = "Fall 2019"
)
RETURN
COUNTROWS ( EXCEPT ( ADM, ENRL ) )
 
Measure not working =
VAR selectedCohortTerm =
SELECTEDVALUE ( 'Dim Cohort Term'[Term Description] )
VAR selectedTrackingTerm =
SELECTEDVALUE ( 'Dim Enroll Term'[Term Description] )
VAR ADM =
CALCULATETABLE (
DISTINCT ( 'Fact Admissions'[Dim Person Key] ),
'Dim Cohort Term'[Term Description] = selectedCohortTerm
)
VAR ENRL =
CALCULATETABLE (
DISTINCT ( 'Fact eNROLLMENT'[Dim Person Key] ),
'Dim Enroll Term'[Term Description] = selectedTrackingTerm
)
RETURN
COUNTROWS ( EXCEPT ( ADM, ENRL ) )
  • problem has been resolved. second filter was applied for both which is why result was blank. thanks for trying

  • sunnysrujan can you check what selectedTrackignTerm is returning? SELECTEDVALUE function will return blank if you are selecting more than one value

      selectTrackingTerm is single selection and yes it is showing value, also i tested the same measure by providing hardcoded values and it gave me accurate results, which is why this is confusing

    Are these two the same data type ? 'Dim Enroll Term'[Term Description] & selectedTrackingTerm

      they should be as selectedTrackingTerm = selectedvalue('Dim Enroll Term'[Term Description]). Meanwhile i created another report to see if its behaving same with other filters (added 4 other slicers) and works perfect. 

      1. If i have to think relationships are wrong here, measure should not work when hardcoded?

      2. same measure with Intersect function works fine too, problem i have when using Except here particularly
