Time duration between multiple events with start and stop

[zinminthant]

Hello,

I would like to calculate duration of Start/Stop of multime events at the time of event Stop. Below is the example. How can I write measure/column in DAX to calculate the duration? 

Date TimeEventsDuration (hr)

1/11/2020 1:00	Start A
1/11/2020 2:00	Stop A	1
1/11/2020 3:00	Start A
1/11/2020 3:00	Others
1/11/2020 4:15	Start B
1/11/2020 5:00	Stop B	0.75
1/11/2020 6:00	Stop A	3
1/11/2020 7:00	Start C
1/11/2020 8:00	Start A
1/11/2020 9:00	Stop C	2
1/11/2020 10:00	Start B
1/11/2020 11:00	Stop A	3
1/11/2020 11:30	Stop B	1.5

Best Regards,

Zin.

Hi @zinminthant 

You'd have to split the Events column to have the type of the event (Start, Stop...)  and the name of the entity the event happens on (A, B...) in separate columns. Best to do this in Power query. Then you can create a column like this:

Duration (hr) =
VAR previousStart_ =
    CALCULATE (
        MAX ( Table1[DateTime] ),
        ALLEXCEPT ( Table1, Table1[Entity] ),
        Table1[Event Type] = "Start",
        Table1[DateTime] < EARLIER ( Table1[DateTime] )
    )
RETURN
    IF ( Table1[Event Type] = "Stop", ( Table1[DateTime] - previousStart_ ) * 24 )
