DAX not working.

[SanketBhagwat]

Hi.

I have created 2 measures using same formula, but one of my DAX is not working and other is working fine.

I have attached screenshots of the same.

Highest Qualifications and Attendance are calculated using same formula;
Highest Qualifications = MAX(WC_Years[QualifiedTeams])

Highest Attendance = MAX(WC_Years[Attendance])

I don't know why it is giving an error.

The 2nd screenshot doesn't show the Qualification measure, you need to clear on it and share the screenshot.

You use ALLSELECTED(WC_Years[Year]) instead of GROUP BY

Hi @Fowmy 

ALLSELECTED() too is giving the same error.

You are getting this error because the TOPN function is returning multiple values. There are multiple years for which the value is equal to Highest Qualifications.

Hi @Fowmy @Aditya_Meshram 

I just noticed that there are multiple year values for which the 'Highest Qualifications' measure is giving the same value.

Do you guys know any DAX which will return only 1 year value.

@SanketBhagwat 

You can use MAXX

Attendnace = 
MAXX (
  VALUES(WC_YEARS[YEAR]),
  [Highest Attendance]
)

 Qualification = 
MAXX (
  VALUES(WC_YEARS[YEAR]),
  [Highest Qualification]
)

Sorry, but the solution you provided didn't gave the correct answer.

@SanketBhagwat 

So you need the year with the highest value:

Qualification = 

MAXX(
    TOPN (
        1,
        ALLSELECTED (WC_YEARS[YEAR]),
        [Highest Qualification]
    ),
    WC_YEARS[YEAR]
)
