Change Matrix Grand total of one measure from sum to average

[rodfernandez]

Hello,
I have the following Matrix
 

Each row come from a different measure. I need to change the grand total of the third row from SUM to Average, so from 100% to 91%, the measure of the third row is:

% este Mes =

VAR m = CALCULATE( MAX( Ejemplo[Mes] ); ALLSELECTED() )   //Select the number of the month selected in the slicer

RETURN IF(                                                 // if the % is bigger than 100% just show 100%, if not show the real %

    [Realizadas a la Fecha]/FIXED([Metas 2018]* m / 12;0;1)>1;

    1;

    [Realizadas a la Fecha]/FIXED([Metas 2018]* m / 12;0;1)   // Calculation of the %, using the numbers from the first row of the matrix ([Metas 2018]), the second row ([Realizadas a la Fecha]) and Variable m that is the selected month in the slicer of the page

)

Thanks

HI rodfernandez,

To be general, you may  modify your measure like pattern below:

% este Mes =
VAR m =
 CALCULATE ( MAX ( Ejemplo[Mes] ); ALLSELECTED () )
VAR total =
 SUMX (
 Ejemplo;
 [Realizadas a la Fecha]
 / FIXED ( [Metas 2018] * m / 12; 0; 1 )
 )
RETURN
 IF (
 DIVIDE ( total; DISTINCTCOUNT ( [Metas 2018] ) ) > 1;
 1;
 DIVIDE ( total; DISTINCTCOUNT ( [Metas 2018] ) )
 )
