NaN error message

[PlastiquesMoore]

Hello to all,

I am pretty much new to Power BI and loving it! I'm still getting used to the Power BI terminology so please bare with me.

This is my Dax formula and I'm getting some "NaN" results. I would like to change this to "0". Could someone please help me?

PPM Externe Médical % Variance = (CALCULATE(sum('Quality (Actuel)'[External PPM - Medical Actuel]) - (sum('Quality (Planifié)'[External PPM - Medical Planifié])))) / (CALCULATE(sum('Quality (Planifié)'[External PPM - Medical Planifié])))

Thanks in advance!

Hi @PlastiquesMoore 

use DIVIDE() function, like 

PPM Externe Médical % Variance = DIVIDE(
CALCULATE(sum('Quality (Actuel)'[External PPM - Medical Actuel]) - (sum('Quality (Planifié)'[External PPM - Medical Planifié]))))
, 
CALCULATE(sum('Quality (Planifié)'[External PPM - Medical Planifié]))
,
0
)

  https://docs.microsoft.com/en-us/dax/divide-function-dax here is some details. you can replace 0 at the end to any value you wish to see instead of NaN

Your formula gave me a DAX error. Figured it out to this. Thanks very much for the help!

PPM Externe Médical % Variance = DIVIDE((CALCULATE(SUM('Quality (Actuel)'[External PPM - Medical Actuel])-(SUM('Quality (Planifié)'[External PPM - Medical Planifié]))));(SUM('Quality (Planifié)'[External PPM - Medical Planifié]));0)

Write the same dax which you have written in original post by using divide function and add zero as third parameter.
Divide(numerator, denominator,0)
Make sure you have closed parenthesis correctly.
You issue will get resolved.

Thanks

@PlastiquesMoore 

now its ok? or try this

PPM Externe Médical % Variance = 
DIVIDE(
(
CALCULATE(SUM('Quality (Actuel)'[External PPM - Medical Actuel]))
-
SUM('Quality (Planifié)'[External PPM - Medical Planifié])
);
SUM('Quality (Planifié)'[External PPM - Medical Planifié]);
0
)
