MoM calculation not working

Hi all!

 

I've been having some problems while I'm calculating MoM change. I'm going to detail the steps for my calculation below:

 

1. Calculate the running total of my variable with the following dax equation:

 

TotalRevenue running total = 
CALCULATE(
	[TotalRevenue]-[LostRevenueSum],
	FILTER(
		ALLSELECTED(DateTable[Date]),
		ISONORAFTER(DateTable[Date], MAX(DateTable[Date]), DESC)
	)
    ,USERELATIONSHIP(subscription[DateSubscribed],DateTable[Date])
)

 

 2. Calculate the MoM change%

 

TotalRevenue MoM% = 
	VAR __PREV_MONTH = CALCULATE([TotalRevenue running total], DATEADD(DateTable[Date], -1, MONTH),
    USERELATIONSHIP(subscription[DateSubscribed],DateTable[Date])
    )
	RETURN
		DIVIDE([TotalRevenue running total] - __PREV_MONTH, __PREV_MONTH,0)

 

 

The problem is that I get wrong results for the curret month (January in this case) as I show below (It should be 3.95%). I'm not sure why this is happening...

 

If I use the MoM change formula with a .[Date] like this, it works but creates an extra month 

 

TotalRevenue MoM% = 
	VAR __PREV_MONTH = CALCULATE([TotalRevenue running total], DATEADD(DateTable[Date].[Date], -1, MONTH),
    USERELATIONSHIP(subscription[DateSubscribed],DateTable[Date])
    )
	RETURN
		DIVIDE([TotalRevenue running total] - __PREV_MONTH, __PREV_MONTH,0)

 

 

Does anyone have any idea what I'm doing wrong?

    ds_br123 mark your date table as date table and don't use .date.

    ds_br123 just to confirm, in visual, you are showing date from date table, not your transaction table. Maybe easy if you share pbix file (remove sensitive information before sharing), you can share it thru one drive/google drive.

    Hi ds_br123 ,

     

    I guess it is because of the date hierarchy used in your table visual that caused this problem.
    If you don't use the date hierarchy and create year, quarter, and month columns, you will get the correct result.'
