Unsupported percentile

[Anonymous]

Hi community!

I'm trying to calculate how much data megabyte use include the top 20% users/account.

I have a table with all kinds of data_MB values in one column, and to calculate the 80th precentile I did:

This measure brought me a value of 1136. Since I need to compare what values are above 1136 in the data_MB column, I calculated an IF-statement to see what accounts use more than 1136 MB, see picture in the DAX-bar. But when putting that value into the table it gives me an error as shown in the picture. Does anyone know how to solve this problem?

When doing an IF-statement without the percentile formula, see picture below, the table works.

Also, when removing the accountid from the table the original IF-statement works. Could it mabye be a dimention thing? 

Many thanks,

Alice

Hi @Anonymous 

Your current [Perc] is a measure right? If so, it should be calculated on the whole table rather than on every accountid. When you add accountid column to the table visual, the [Perc] is evaluated for every acountid so it couldn't return the correct result. Instead, you can try the following measure

test =
IF (
    SUM ( 'table'[data_MB] ) > CALCULATE ( [Perc], ALLSELECTED ( 'Table' ) ),
    1,
    0
)
