compute time difference between two lines in table

[seb_BMW]

I have the following table:

Nr      position       time

1            in              12:23:10

2            in              12:25:19

1            out            12:28:59

3            in              13:00:00

2            out            13:02:10

and want to compute the time difference between in and out of each number, so that i have in this example:

Nr          diff

1            00:05:49

2            00:06:51

3            null     (or another text like "in")

how can i do this ? 

thank you very much

You're looking for the Pivot function.

• Pivot on Position (Value is Time, and be sure not to aggregate)
• Use M to subtract the resulting in/out column values
• Convert datatype to the Duration type

The line of M:

#"Added Difference" = Table.AddColumn(#"Pivoted Column", "Diff", each [out] - [in]),

Hi @seb_BMW,

Have you worked it out? If so, would you please mark the corresponding reply as an answer? If you still have any concern, please feel free to ask.

Hi @seb_BMW,

Alternatively, you can achieve this in DAX.

Create a calculated table based on below formula.

new table =
SUMMARIZE (
    'time difference',
    'time difference'[Nr],
    "time diff", DATEDIFF (
        MIN ( 'time difference'[time] ),
        MAX ( 'time difference'[time] ),
        SECOND
    )
)

Add a calculated column in order to format the time difference.

Column =
IF (
    'new table'[time diff] = 0,
    BLANK (),
    INT ( 'new table'[time diff] / 3600 )
        & ":"
        & INT ( MOD ( 'new table'[time diff], 3600 ) / 60 )
        & ":"
        & MOD ( MOD ( 'new table'[time diff], 3600 ), 60 )
)  

Best regards,
