Divide by Zero error

Hi All,   I have this measure that's causing error due to divide by zero error.  How can I get pass this? % Change =  SUMX(Summary, Summary[CQ] - Summary[PYQ]/(Summary[PYQ])) Thanks Ejyks

    Think this should work:

    % Change =
SUMX (
    Summary,
    DIVIDE( 
    	(Summary[CQ] - Summary[PYQ] ),  //Numerator
        Summary[PYQ] ,                  //Denominator
        "If Error, put something here!" //Alternate Result
	)
)

Let's try this one.  Basically added in logic that if either the absolute values of the values we need to divide is  0, then we want a 0 there, if not to the normal divide.  

 

Just need to substitute out my generic table and measures for yours:

% Change = 
SUMX( 
    VALUES( Table1[Index] ),
    CALCULATE(
    IF (
        OR ( 
            ABS([Total Item1] ) = 0,
            ABS( [Total Item 2]) = 0
        ),
        0,            
         DIVIDE( 
            ( [Total Item 2] - [Total Item1]),
            [Total Item1]
        )
    )
    )
)

Basically I got confused by the your last formula so I changed the whole formula to use an IF statement and it now works for me. The -1.0 is what gives -100% when converted to percentage.

 

% Change PYQ = IF(DIVIDE(SUM(Summary[CQ])- SUM(Summary[PYQ]), //Numerator
                   SUM(Summary[PYQ])                     //Denominator
                   ) = -1.0, 0,
DIVIDE(SUM(Summary[CQ])- SUM(Summary[PYQ]), //Numerator
                   SUM(Summary[PYQ])))
