Dynamic N-Value (TOPN) for Least Popular Day Calculation

[arif_tsrm]

I am trying to calculate Least popular day using the following DAX, but I am getting the fixed result ( Friday ) although there is no value ( blank) in friday, I think the result is fixed Friday is  only for that  I am using  fixed N-Value 5, is there any way we can set the N-Value dynamically?

LeastPopularDayOfWk=

FIRSTNONBLANK (
TOPN (
5,
CALCULATETABLE (
VALUES ( DimDayName[DayName] ),
FILTER ( DimWP, DimWP[WP] <> "Remote" )
),
[%Of_Attendance_By_DayForM/LPD]
),
1
)

Hi @arif_tsrm ,

I create a table as you mentioned.

Then I create a measure and here is the DAX code.

Measure =
VAR _Lastest =
    CALCULATE ( MAX ( 'Table'[Number] ), ISBLANK ( 'Table'[Attendance] ) )
RETURN
    CALCULATE (
        MAXX ( FILTER ( 'Table', 'Table'[Number] = _Lastest ), 'Table'[DayShort] ),
        ISBLANK ( 'Table'[Attendance] )
    )

Now you can use dynamic N-Value (TOPN) for least popular day.

Thanks for your reply , you have created the table is data table but my mentioned table is a visualization , I want to calculate the least popular day based on value of the measure  [%Of_Attendance_By_DayForM/LPD],   if in any days the  [%Of_Attendance_By_DayForM/LPD] is blank then those days we not consider . for this data scenerio the least popular day will be Tuesday and Wednesday ( because the lowest value is 50%) instead of Friday.

Hi @arif_tsrm ,

I do some changes on my DAX codes.

Measure 2 = 
VAR _A =
    MINX (
        FILTER ( 'Table', NOT ( ISBLANK ( 'Table'[Attendance] ) ) ),
        'Table'[Attendance]
    )
RETURN
    LOOKUPVALUE ( 'Table'[DayShort], 'Table'[Attendance], _A )

Then you can see that it will return you the smallest value other than blank.
