Rolling 6 months

[Anonymous]

Hi Experts

Trying to work out the rolling 6 months to start at a specific date in my table - my measure is (but i cannot see the error)

Rolling 6 mnth = 
VAR _Min = Min(BM Historic[Month Year])

BAR _Startdate = Edate(_min,48)

Return

Calculate(Sum(BM Historic [Value]),Max(_startdate),-6,month))

Hey @Anonymous ,

I didn't understand your DAX measure and I also think it can't work as there are some errors.

If you want to get rolling 6 months data, you should try the following approach:

Rolling 6 mnth =
CALCULATE(
    Sum('BM Historic'[Value]),
    DATESINPERIOD(
        'DateTable'[Date],
        MAX('DateTable'[Date]),
        -6,
        MONTH
    )
)

Be aware, that you need a proper date table in order for the time intelligence functions to work.

If you need any help please let me know.

Hi Denis, What i was trying to do is start my rolling 6 months from date index number 25 which is Feb 2017 and ignore all dates before this date..... Is this possible?

Hey @Anonymous ,

I don't know what you mean with index number 25 as that's also not in your file.

But you can set the date in the measure above. Instead of "MAX('DateTable'[Date])" you can also just write "DATE( 2017, 2, 25)" as start date.

If you need any help please let me know.
