Forward rolling total demand

[Anonymous]

The values are spread over different attributes such as Production, Demand, ETA etc. I need to find out a 3 month total demand calculated from any selected date. Following are the DAX i tried. But the values are incorrect. How to correct this?

DAXs used to calculate 3 month total demand:

3 months total values =

VAR LastDate_ = LASTDATE(Append1[Week Start date])

RETURN

    CALCULATE(

        SUM(Append1[Value]),  

        DATESINPERIOD(Append1[Week Start date], LastDate_, 3, MONTH)

    )

3 months total demand = CALCULATE([3 months total values],FILTER(Append1, Append1[Attributes]="Demand"))

Hi, @Anonymous ;

Try it.

3 months total values = 
VAR LastDate_ = LASTDATE(Append1[Week Start date])
RETURN
   IF(MAX('Append1'[Attributes])= "Demand",CALCULATE(
        SUM(Append1[Value]),  
        DATESINPERIOD(Append1[Week Start date], LastDate_,- 3, MONTH),Append1[Attributes]="Demand"))

the final show:

@Anonymous , For all time intelligence functions use date table

VAR LastDate_ = LASTDATE(Append1[Week Start date])
RETURN
CALCULATE(
SUM(Append1[Value]),
DATESINPERIOD(Date[date], LastDate_, 3, MONTH)
)

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
