Monthly comparison over years

Hello.

 

I have a month comparison (last year LY and current year CY).  I have a data starting NOV 2021.  How do you make the month comparison start in NOV 2021 instead of JAN 2022.  How do you compare (monthly, year over another year) based on last X months?  Thanks.

There is also a separate DATE TABLE created using a query:

Hi @Oros ,

 

Please try the measure.

 

Rolling x months = 
VAR x = 3
RETURN
    CALCULATE (
        SUM ( 'SALES TABLE'[Sales] ),
        DATESINPERIOD ( 'DATE TABLE'[Date], MAX ( 'DATE TABLE'[Date] ), -1 * x, MONTH )
    )

Hello @v-kkf-msft ,

 

Thank you for your reply.  How and where do you insert the ROLLING X MEASURE in this matrix table?

Hi @Oros ,

 

I simply add the measure and Sales to the Values field of the matrix, and I switch the value to rows in the attribute for easier comparison.

Hello @v-kkf-msft ,

 

Thank you for your reply.  I just realized that your solution if ROLLING X MONTHS.  What I was looking for was simply to start the month-to-month comparison from NOVEMBER 2021 to NOVEMBER 2022, instead of January-January.  Is there a way to show each month starting November 2021? Thanks again.

Hi @Oros ,

 

I am not sure if I understood your question correctly. If you only need to compare data in the range 2021-11 to 2022-11, please try

 

Rolling x months = 
VAR x = 3
VAR diff =
    CALCULATE (
        SUM ( 'SALES TABLE'[Sales] ),
        DATESINPERIOD ( 'DATE TABLE'[Date], MAX ( 'DATE TABLE'[Date] ), -1 * x, MONTH )
    )
VAR SelectDate =
    FORMAT ( MAX ( 'DATE TABLE'[Date] ), "yyyymm" )
RETURN
    IF ( SelectDate >= "202111" && SelectDate <= "202211", diff )

OK So the idea is adding new colums to your calendar table and slice by them , same as fiscal year . 

note ;

please dont forget to change the current column to the new colum in your dax measre .
