Month over Month Comparison from previous year

[tulsi]

Hey,

I have three columns in my dataset, month, task name and hours. I have to compare the % change of hours by task name month over month from last year. Can you help me with this.

Thanks

@tulsi ,

Generally, you can create a measure using DAX below:

Change =
VAR Current_Month =
    MONTH ( Table[Date] )
VAR Previous_Month = Current_Month - 1
VAR Current_Month_Hours =
    CALCULATE (
        SUM ( Table[Hours] ),
        FILTER ( Table, MONTH ( Table[Date] ) = Current_Month )
    )
VAR Previous_Month_Hours =
    CALCULATE (
        SUM ( Table[Hours] ),
        FILTER ( Table, MONTH ( Table[Date] ) = Previous_Month )
    )
RETURN
    IF (
        YEAR ( Table[Date] )
            >= YEAR ( TODAY () ) - 1,
        Current_Month_Hours - Previous_Month_Hours / Previous_Month_Hours,
        BLANK ()
    )

Hey,

I tried your DAX formula to create a calculated formula like this;

Change =
VAR Current_Month =
Month (Final[Month])
VAR Previous_Month = Current_Month - 1
VAR Current_Month_Hours =
CALCULATE(
SUM( Final[Total Number of Hours]),
FILTER(Final,MONTH(Final[Month])=Current_Month)
)
VAR Previous_Month_Hours =
CALCULATE(
SUM(Final[Total Number of Hours]),
FILTER(Final,MONTH(Final[Month])=Previous_Month)
)
RETURN
IF(
YEAR(Final[Month])
>= YEAR( TODAY() )-1,
Current_Month_Hours - Previous_Month_Hours / Previous_Month_Hours,
BLANK()
)

Now the result that I want is % change in the total number of hours by task name month by month but i'm getting something like this;

@tulsi ,

Click on the change column and click Modeling-> Format, change the format to percentage.

Thanks for the reply. Do I need to create a calendar table first? Sorry I'm new to powerBI. The date mentioned in the third line 

 MONTH ( Table[Date] 

Is this from the calendar table?

Thanks
