Breaking Punch In and Punch Out DateTime columns into shift categories

Instead of a matrix result like you have, I suggest you shoot for a classification of each punch as follows:

1) Isolate the TIME portion from the Date. 

2) Create a calculated column that looks at TIME and write a nested IF statement in DAX to determine if it is DAY, EVENING or NIGHT. 

Hope that helps.

Question, how would you classify someone that punched IN at 1000 and OUT at 1800?

Hi  dcrow5378 ,

 

Thanks for the reply from ToddChitt , please allow me to provide another insight:  

 

Here are the steps you can follow：

1. Create calculated column.

Day Hours =
VAR _daystart =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Day" ),
        [Start]
    )
VAR _datend =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Day" ),
        [End]
    )
VAR _value =
    SWITCH (
        TRUE (),
        AND (
            [In] >= _daystart
                && [In] < _datend,
            [Out] > _daystart
                && [Out] <= _datend
        ), [Out] - [In],
        AND ( [In] >= _daystart && [In] < _datend, [Out] > _datend ), _datend - _daystart
    )
RETURN
    IF (
        _value = BLANK (),
        BLANK (),
        VALUE ( LEFT ( _value, LEN ( _value ) - 2 ) )
            + DIVIDE ( VALUE ( RIGHT ( _value, 2 ) ), 60 )
    )

Evening Hours =
VAR _eveningstart =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Evening" ),
        [Start]
    )
VAR _eveningend =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Evening" ),
        [End]
    )
VAR _daystartday =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Day" ),
        [Start]
    )
VAR _dayendday =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Day" ),
        [End]
    )
VAR _value =
    SWITCH (
        TRUE (),
        AND ( [In] >= _eveningstart && [In] < _eveningend, [Out] <= _eveningend ), [Out] - [In],
        AND ( [In] >= _eveningstart && [In] < _eveningend, [Out] > _eveningend ), _eveningend - [In],
        AND ( [In] < _eveningstart, [Out] <= _eveningend && [Out] > _dayendday ), [Out] - _eveningstart
    )
RETURN
    IF (
        _value = BLANK (),
        BLANK (),
        VALUE ( LEFT ( _value, LEN ( _value ) - 2 ) )
            + DIVIDE ( VALUE ( RIGHT ( _value, 2 ) ), 60 )
    )

Night Hours =
VAR _nightstart =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Night" ),
        [Start]
    )
VAR _nightend =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Night" ),
        [End]
    )
VAR _eveningstart =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Evening" ),
        [Start]
    )
VAR _eveningend =
    MINX (
        FILTER ( ALL ( 'shift break times' ), 'shift break times'[Shift] = "Evening" ),
        [End]
    )
VAR _value =
    SWITCH (
        TRUE (),
        [In] >= _nightstart
            && [Out] <= _nightend,
            2400 - [In] + [Out],
        AND (
            [In] < _nightstart
                && [In] >= _eveningstart,
            [Out] >= _nightend
                && [Out] > _eveningend
        ), [Out] - _nightstart
    )
RETURN
    IF (
        _value = BLANK (),
        BLANK (),
        VALUE ( LEFT ( _value, LEN ( _value ) - 2 ) )
            + DIVIDE ( VALUE ( RIGHT ( _value, 2 ) ), 60 )
    )

2. Result:
