如何在Power BI中的“计算所得”列中使用度量？

Question

I calculate a quartile in a measure :

 Percentile1_25 = CALCULATE(PERCENTILEX.EXC(DWH;DWH[AREA];0,25);DWH[TYPE_APPART] = "1")

that I want to use in a calculated column :

 COL= if(DWH[TYPE_APPART] = "1"; if(DWH[AREA]>[Percentile1_75];"a";"b");"c")

but I have this error :

 "The value of the percentile must be in the range 1 / (N + 1) .. N / (N + 1) included, where N is the number of data values."

Does someone know this error ?

If I put the real value of Percentile1_75 it's ok, but the measure is not accepted.

Thx

The calculated column is not returning expected result because the measure and the calculated column has a different row context. You may try to combine both formula into one to avoid such behavior:

ie

column = 
VAR measure = measure formula
RETURN column formula

eg

COL =
VAR Percentile1_25 = CALCULATE(PERCENTILEX.EXC(DWH;DWH[AREA];0,25);DWH[TYPE_APPART] = "1")
RETURN if(DWH[TYPE_APPART] = "1"; if(DWH[AREA]>Percentile1_25;"a";"b");"c")
