Calculate Time Between

Hi all,   How can create the column 'Break' below?   It calculates the time between the end of the shift and start of the next one. They can be on different dates but have to be the next day work...

    Hi HenryJS ,

     

    Start_time = 
VAR __start = MAX(Sheet7[Start])
RETURN
DATE(2020, 1, 2) + __start
    End_time = 
VAR __end = 
CALCULATE(
    MAX([End]),
    FILTER(
        ALL(Sheet7),
        Sheet7[Timesheet ID] = MAX(Sheet7[Timesheet ID]) && Sheet7[Date] < MAX(Sheet7[Date]) 
    )
)
RETURN
IF(
    __end <> BLANK(),
    DATE(2020,1,1) + __end,
    BLANK()
)
    Measure 2 = 
IF(
    [End_time] <> BLANK(),
   [Start_time] - [End_time],
    TIME(0,0,0)
)

     

    Best regards,

HenryJS See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/339586.
The basic pattern is:
Column = 
  VAR __Current = [Value]
  VAR __Previous = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Value])
RETURN
  __Current - __Previous

 

In your case you would use DATEDIFF between your row and the previous row once you extract the necessary values.
