Calculating days between dates and ignore if blank

[LewisH]

I have two dates in a table, Registering Day and Day out. 

There will always be a registering date, but not always a day out. I need to work out the average daby between but this is casuing errors beciase one of the days will be blank. I have started with something like this but can anyone guide me on how to correct it. Thanks

Workingdays = CALCULATE(SUM('DateKey'[IsWorkingDay]), DATESBETWEEN(DateKey[Date],'Put Away Headers'[Registering_Date],'Put Away Headers'[Day_Out])) -- Here i need to filter out blank "Day Out"

Hi @LewisH,

If I understand you correctly, the formula below should work in your scenario. 

Workingdays =
IF (
    ISBLANK ( 'Put Away Headers'[Day_Out] ),
    BLANK (),
    CALCULATE (
        SUM ( 'DateKey'[IsWorkingDay] ),
        DATESBETWEEN (
            DateKey[Date],
            'Put Away Headers'[Registering_Date],
            'Put Away Headers'[Day_Out]
        )
    )
)

Regards

Hi,

Does this work?

=CALCULATE(SUM('DateKey'[IsWorkingDay]),FILTER('Put Away Headers','Put Away Headers'[Day_out]<>BLANK()),DATESBETWEEN(DateKey[Date],'Put Away Headers'[Registering_Date],'Put Away Headers'[Day_Out]))
