Hi v-jiascu-msft

sent to your privte inbox 

please check and help me to correct the formula

thanks 

Hi shado26,

Please upgrade your Desktop to the latest version from https://www.microsoft.com/en-us/download/details.aspx?id=45331. Then you can use the formula freely. (No error about Datediff)

The question is how to define weekend when start and end aren't in a single day.

Best Regards,

Hi v-jiascu-msft

i want to thank you to help me on this its work fine now after instal the new version of Power PI 

i have one question to ask 

can we add on this to calculate the SLA from working hours

like Ex 

if i received order on 5:30 PM  

and approved next working day on 9:30 

i calculation of SLA should be 30 min in evening and 30 min in morning to this will be met the SLA

another Ex 

if i received order on 5:30 PM  

but approved next working day on 10:30 

this SLA for this will be 2 h for this should count as faild 

many thanks

Hi shado26,

I have a similar case today. You can add a new column to computer the work hours only. Please check the demo here.

AllInOne =
VAR standardStart =
    IF (
        TIMEVALUE ( [Start Time] ) < TIME ( 9, 0, 0 ),
        DATEVALUE ( [Start Time] ) + TIME ( 9, 0, 0 ),
        IF (
            TIMEVALUE ( [Start Time] ) > TIME ( 17, 0, 0 ),
            DATEVALUE ( [Start Time] ) + TIME ( 17, 0, 0 ),
            [Start Time]
        )
    )
VAR standardEnd =
    IF (
        TIMEVALUE ( [End Time] ) < TIME ( 9, 0, 0 ),
        DATEVALUE ( [End Time] ) + TIME ( 9, 0, 0 ),
        IF (
            TIMEVALUE ( [End Time] ) > TIME ( 17, 0, 0 ),
            DATEVALUE ( [End Time] ) + TIME ( 17, 0, 0 ),
            [End Time]
        )
    )
VAR businessDay =
    CALCULATE (
        SUMX ( DateTable, [IsWorkday] ),
        FILTER (
            'DateTable',
            'DateTable'[Date] > [Start Time].[Date]
                && 'DateTable'[Date] < [End Time].[Date]
        )
    )
RETURN
    IF (
        [Start Time] > [End Time],
        9999,
        IF (
            [Start Time].[Date] = [End Time].[Date],
            DATEDIFF ( standardstart, standardend, HOUR ),
            [Business Days] * 8
                + DATEDIFF ( TIMEVALUE ( standardstart ), TIME ( 17, 0, 0 ), HOUR )
                + DATEDIFF ( TIME ( 9, 0, 0 ), TIMEVALUE ( standardend ), HOUR )
        )
    )
