    Hi kumsha1 ,

    You can try to below calculate column formula to get last end DateTime and calculate the duration between two DateTime fields:

    hour = 
VAR diff =
    DATEDIFF (
        CALCULATE (
            MAX ( 'Table'[Delay End] ),
            FILTER (
                'Table',
                [Unit] = EARLIER ( 'Table'[Unit] )
                    && [Current Delay Start] < EARLIER ( 'Table'[Current Delay Start] )
            )
        ),
        [Current Delay Start],
        SECOND
    )
RETURN
    diff / 3600
