Calculate Top 10% using percentiles by Year

[meghansh]

Hi Folks,

I am stuck at this problem. I have the following data:
I need to calculate Top 10% Users (ID) based on the amount for each year (using year as a slicer). Thank you.

ID	Year	Amount
5487	2020	205987
5487	2021	152659
5487	2022	548751
5459	2019	326985
5459	2020	321549
5459	2021	547854
5459	2022	652301
4589	2019	-987326
4589	2020	12545

5658	2020	6456
5658	2021	15654
5658	2022	48998
8799	2020	178469
8799	2021	54545
1023	2019	81212
4665	2019	851025

Hi,

These measures work

ID count = COUNTROWS(Data)

10% of ID count = ROUNDUP(0.1*[ID count],0)

Total = SUM(Data[Amount])

Measure = CALCULATE([Total],TOPN([10% of ID count],ALL(Data[ID]),[Total]),VALUES(Data[ID]))

Hope this helps.

Hi, @meghansh 

You can try the following DAX.

DAX:

Rank = 
RANKX (
    FILTER ( 'Table', 'Table'[Year] = EARLIER ( 'Table'[Year] ) ),
    'Table'[Amount],
    ,
    DESC,
    SKIP
)

Filter ID = 
VAR _rows =
    CALCULATE (
        COUNTROWS ( 'Table' ),
        'Table'[Year] = SELECTEDVALUE ( 'Table'[Year] ),
        ALL ( 'Table' )
    )
VAR _10Percent = _rows * 0.1
VAR _result =
    IF ( SELECTEDVALUE ( 'Table'[Rank] ) <= _10Percent, 1, 0 )
VAR _result1 =
    IF ( _rows < 20 && SELECTEDVALUE ( 'Table'[Rank] ) = 1, 1, 0 )
RETURN
    IF ( ISFILTERED ( 'Table'[Year] ), IF ( _rows < 20, _result1, _result ), 1 )
