measure which calculates values based on value of previous month

[TechR21]

Hi,

Im trying to create a measure that calculates the cumulative value. This is calculated with the formula:

cumulative = cumulative value previous month + total costs

Only May contains a cumulative value, which is 1,058,333.40. With this value (from a column) I have to calculate the cumulative value of the other months.

Im trying a few things but I cant seem to get the correct values, only for June, because for July he takes the empty value of Cumu column for June + total costs.

the measure i use:

Cumulative = Calculate(MIN('table1'[Cumu])  + [total costs]  , DATEADD('Query1'[Date], -1, MONTH))

Anyone an idea how to get this working?

Hi @TechR21 

@Greg_Deckler explains in the video to get a running total https://www.youtube.com/watch?v=meh3OkgFYfc&list=PLoibEIc7heYNZbnY4CTCtg2tjEcMh8WbZ&index=3 

You can also try

Costs Running Total = 
    VAR maxdate = MAX(Cost_Table[Date])
    RETURN
    CALCULATE(
        SUM(Cost_Table[Cost Amount]),
        Cost_Table[Date] <= maxdate,
        ALL(Cost_Table[Date])
    )

Thanks

Joe

but your measure doesnt include the table1[cumu] value so it wont give the correct values.

the May value (1,058,333.40) is the starting point. Together with the costs of that month , that is the cumulative value
