Rolling 3 month calculation

[mmills2018]

Hello,

i am calculating rolling 3 month annualized turnover, but something is off.  My term count for March is 163, when i annualize 163 i get 652. My calculation is only annualzing March and not March and the 2 months prior.

here is my measure - any ideas how i can get it to sum Jan terms, feb terms, march terms and then annualize (X4)?

VAR LatestMonth = LASTDATE(Snapshots[Data as of])

VAR Prior3rdMonth = FIRSTDATE(DATESINPERIOD(Snapshots[Data as of],LatestMonth,-3,month) )

return

CALCULATE(DISTINCTCOUNTNOBLANK('Snapshots'[AssociateID]), 'Snapshots'[Gender]="Female",'Snapshots'[Alt Term Date]<>BLANK(), 'Snapshots'[TerminationPrimaryTerminationCategory]="Voluntary",'Snapshots'[TerminationBusinessProcessReason]<>"Retirement", 'Snapshots'[TerminationBusinessProcessReason]<>"Assignment/Contract End", 'Snapshots'[TerminationBusinessProcessReason]<>"Deceased", 'Snapshots'[TerminationBusinessProcessReason]<>"Did Not Start", 'Snapshots'[TerminationBusinessProcessReason]<>"Failure to Provide Required Employment Eligibility", DATESBETWEEN('Date Table'[Date],Prior3rdMonth,LatestMonth))*4

Hi @mmills2018 ,

Based on your description, the DAX formula you created does not seem to see any logical problems. 

Could you please share some sample data and the expected result to have a clear understanding of your question? I can do some tests for you. 😊 If the information is sensitive please share it after removing private message.

All the formulae in this thread are incorrect. This is because any time-intel function needs a real date table to work properly. Please read the documentation on DATESINPERIOD: https://dax.guide/datesinperiod

thanks, my initial approach i did use a real data table, below is my measure:

VAR LatestMonth = LASTDATE('Date Table'[Date])

VAR Prior3rdMonth = FIRSTDATE(DATESINPERIOD(Snapshots[Data as of],LatestMonth,-3,month) )

return

CALCULATE(

DISTINCTCOUNTNOBLANK( 'Snapshots'[AssociateID] ),

'Snapshots'[Gender] = "Female",

'Snapshots'[Alt Term Date] <> BLANK(),

'Snapshots'[TerminationPrimaryTerminationCategory] = "Voluntary",

'Snapshots'[TerminationBusinessProcessReason] <> "Retirement",

'Snapshots'[TerminationBusinessProcessReason] <> "Assignment/Contract End",

'Snapshots'[TerminationBusinessProcessReason] <> "Deceased",

'Snapshots'[TerminationBusinessProcessReason] <> "Did Not Start",

'Snapshots'[TerminationBusinessProcessReason] <> "Failure to Provide Required Employment Eligibility",

DATESINPERIOD(

'Date Table'[Date],

LatestMonth,

-3,

MONTH

)

) * 4

and this is what i return.  The issue i am having is i want to calculate rolling 3 month annualized turnover by month, so for March i should see 1628, it is also only showing me 3 months of data, i want to see a years worth of data, so Feb would include Dec, Jan and Feb terms, but i need a moving rolling count.  any ideas on how to do this?

Hey @mmills2018 ,

I think your approach with the date calculation is a little too complicated. Just try to use DATESINPERIOD as a calculate modifier, that seems to be more easy and also more logical for me:

MyMeasure =
VAR LatestMonth =
    LASTDATE( Snapshots[Data as of] )
RETURN
    CALCULATE(
        DISTINCTCOUNTNOBLANK( 'Snapshots'[AssociateID] ),
        'Snapshots'[Gender] = "Female",
        'Snapshots'[Alt Term Date] <> BLANK(),
        'Snapshots'[TerminationPrimaryTerminationCategory] = "Voluntary",
        'Snapshots'[TerminationBusinessProcessReason] <> "Retirement",
        'Snapshots'[TerminationBusinessProcessReason] <> "Assignment/Contract End",
        'Snapshots'[TerminationBusinessProcessReason] <> "Deceased",
        'Snapshots'[TerminationBusinessProcessReason] <> "Did Not Start",
        'Snapshots'[TerminationBusinessProcessReason] <> "Failure to Provide Required Employment Eligibility",
        DATESINPERIOD(
            Snapshots[Data as of],
            LatestMonth,
            -3,
            MONTH
        )
    ) * 4

I presonally also would "clean up" the TerminationBusinessProcessReason with NOT IN, but that is optional 😉:

MyMeasure =
VAR LatestMonth =
    LASTDATE( Snapshots[Data as of] )
RETURN
    CALCULATE(
        DISTINCTCOUNTNOBLANK( 'Snapshots'[AssociateID] ),
        'Snapshots'[Gender] = "Female",
        'Snapshots'[Alt Term Date] <> BLANK(),
        'Snapshots'[TerminationPrimaryTerminationCategory] = "Voluntary",
        NOT ( 'Snapshots'[TerminationBusinessProcessReason]
            IN {
            "Retirement",
            "Assignment/Contract End",
            "Deceased",
            "Did Not Start",
            "Failure to Provide Required Employment Eligibility"
        } ),
        DATESINPERIOD(
            Snapshots[Data as of],
            LatestMonth,
            -3,
            MONTH
        )
    ) * 4
