Passing a Variable not working

[Anonymous]

Hi everyone,

I hope you will be able to help me to understand why the variables in DAX do not work as expected.

If I create a measure as the below, it doesn't work (doesn't return the desired outcome):

x_Achieved = 
VAR CurrentQTR = LOOKUPVALUE(Dates[Academic_Year_Quarter],Dates[Date],MAX(c_Enrolments[Date Exported On]))
VAR IsAchieved = FILTER(c_Enrolments,c_Enrolments[CompletionID]=2 && c_Enrolments[OutcomeID]=1 )
RETURN CALCULATE(COUNTROWS(c_Enrolments),FILTER(Dates_AED,Dates_AED[Academic_Year_Quarter]=CurrentQTR),IsAchieved)

Once I change the CurrentQTR to an actual string, it seems to work correctly (returns what is expected):

x_Achieved = 
//VAR CurrentQTR = LOOKUPVALUE(Dates[Academic_Year_Quarter],Dates[Date],MAX(c_Enrolments[Date Exported On]))
VAR IsAchieved = FILTER(c_Enrolments,c_Enrolments[CompletionID]=2 && c_Enrolments[OutcomeID]=1 )
RETURN CALCULATE(COUNTROWS(c_Enrolments),FILTER(Dates_AED,Dates_AED[Academic_Year_Quarter]="22/23 - Q4"),IsAchieved)

When I evaluate the CurrentQTR calculated using the LOOKUPVALUE and pass it into a Card visual, it shows exactly the desired value, "22/23 - Q4".

I am baffled as I have no idea why it has decided not to work...

I am sure it must be something silly and simple, but I am stuck.

Many thanks for your time 🙂

hi @Anonymous 

most probably because the filter context is different. What filter context do you have for your first code? filter context includes visual columns, rows, axis, filter pane setting, slicer selection. 

In your first code, try to

RETURN CurrentQTR

what do you get?
