measures to find difference between current vs previous month

Hi,

 

To calc the variance between current vs previous month amounts, I use this formula:

    AdsPromo Var = if([AdsPromo LM] = BLANK(), 0, 
          [AdsPromo]-[AdsPromo LM])

 

For Feb17, the AdsPromo Var amount is still 0 using the above formula when it should be 464 (464-0). Kindly advise on how resolve the error in the measure/DAX.

    Hi Anonymous ,

     

    Assuming that your source table is similar to below -

     

    Source

     

    If you are looking for a measure, use below DAX query - 

     

     

    AdsPromo Var =
VAR current_Month =
    CALCULATE ( SUM ( 'Table'[AdsPromo] ) )
VAR previous_Month =
    CALCULATE ( SUM ( 'Table'[AdsPromo] ), PREVIOUSMONTH ( 'Table'[Month-S] ) )
VAR AdsPromoVariance = current_Month - previous_Month
RETURN
    AdsPromoVariance

     

     

    The Month-S column should be the date type. 

     

    Here is the output

     

    Output

     

     

     

     

     

     

    Regards,

    Nandu Krishna

    Thanks, nandukrishnavs .

     

    All is good. 

    In fact, I have also managed to create the variance percentage subsequently.
