Accumulate data over a period on a measures not working

[Puttsson]

Hey,

I'm trying to sum up the R12 value for a column that I created. But it doesn't work.

RM R12 is supposed to show R12-value of RMprevmonth

It seems somewhat random what's shown. Am I missing something in the measures?

vFactRM har a relationship to DimDates on [RevenueDate] to DimDate[Date]

This measures shows the actual month or the previous month for future months

RMprevmonth =

VAR _lastSalesDate = CALCULATE(MAX(vFactRM[RevenueDate]),ALL(vFactRM))

VAR _lastSalesMonth = CALCULATE(MAX(DimDate[Date]),ALL(DimDate),DimDate[Date]=_lastSalesDate)

VAR _lastMonthTotal = CALCULATE(SUM(vFactRM[AmountInSEK]),ALL(DimDate),DimDate[Date]=_lastSalesMonth)

VAR _thisMonth = MAX(DimDate[Date])

VAR _prevMonthSales = CALCULATE(SUM(vFactRM[AmountInSEK]),PREVIOUSMONTH(DimDate[Date]))

RETURN

IF(_thisMonth<=_lastSalesMonth,_prevMonthSales,_lastMonthTotal)  //SUM(vFactRM[AmountInSEK])

RM R12 =
CALCULATE (
[RMprevmonth],
DATESINPERIOD ( DimDate[Date], MAX ( DimDate[Date] ), -12, MONTH )
)

Thanks!

Hi,

Thanks for the reply

What I want to achieve is a rolling 12 months value in "RM R12". So for each month it should be the sum of the last 12 months of RMprevmonth.

The relationship:

vFactRM has a relationship to DimDate on [RevenueDate] to DimDate[Date]

Sorry I can't attach a pbix-file. 

Thanks!

Hi @Puttsson ,

There are seems two tables inside. What is the relationship between the 2 tables ? What are the data in the DimDate Table  like? How about in the vFactRM Table?

Could you please provide more details with your desired output and pbix file without privacy information?
