PercentileX.INC returns blank

Hi all,   I'm trying to do a simple percentilex.inc calculation but the result is returning blank unless I manually select all the values I am grouping on. The DAX is  PERCENTILEX.INC(VALU...

    Thank you, you helped me get on the right track.

    I got it working with

     

     

    = PERCENTILEX.INC(
			Summarize(
				Facttable,
				Table1[Group1])
			),
			[KPI],
			0.5
		)

     

     

    I still have no idea why values acted as it did though.

    Once I was happy it was workng I enhanced it to enable me to filter out smaller groups

     

     

    KPI = PERCENTILEX.INC(
			FILTER(
				ALLSELECTED(Table1[Group1]),
				[KPI_Denominator] >= 5
			),
			[KPI],
			0.5
		)

itchyeyeballs , Try below method

 

Use ALL Function: Modify your DAX formula to use the ALL function to ignore any filters on Table1[Group1]. This can help in ensuring that the percentile calculation considers all values regardless of the slicer selection.

 

PERCENTILEX.INC(ALL(Table1[Group1]), [KPI], 0.5)


Check KPI Calculation: Ensure that the [KPI] measure is correctly calculated and does not return blank or error values. You can add a check to handle any potential division by zero or other issues:

 

KPI = IF(
ISBLANK([KPI_Denominator]) || [KPI_Denominator] = 0,
BLANK(),
DIVIDE([KPI_Numerator], [KPI_Denominator])
)
Debugging: Create a table visualization to display the values of Table1[Group1] and [KPI] to ensure that the data is as expected and there are no unexpected blanks or errors.
