Measure to finde time difference between two ordered timestamps within one category

Hi charlineklapu .

According to your description, here is my solution, and please follow these steps.

Firstly, process the data and make sure that your columns "Opened on" and "Timestamp" are Date/time format.

And then use Power Query to add an index column.

And then create a calculated column.

Column =
VAR _a =
    CALCULATE (
        MAX ( 'Table'[Timestamp] ),
        FILTER ( 'Table', [Index] = EARLIER ( 'Table'[Index] ) + 1 )
    )
VAR _b =
    DATEDIFF ( _a, [Timestamp], HOUR )
VAR _c =
    CALCULATE (
        MIN ( 'Table'[Timestamp] ),
        FILTER (
            'Table',
            [Customer] = EARLIER ( 'Table'[Customer] )
                && [Timestamp] > EARLIER ( 'Table'[Timestamp] )
        )
    )
RETURN
    SWITCH (
        TRUE (),
        [Status] = "Request Processed"
            && ISBLANK ( _c ), "FCR",
        [Status] = "Request Processed"
            && _b > 24, "FCR",
        [Status] = "Request Processed"
            && _b < 24, "n.FCR"
    )

Final output:

I attach my sample below for your reference.
