Time Difference between consecutive rows

[ziyabikram96]

I am getting error when ever consective c/in or C/out occure in calaculating time difference but whenever consecutive occure I want to pick maximum from the C/out and minimum from C/In for further clarification I am attaching a screenshot please help me in this 

Thank you

Thank you

Hi, @ziyabikram96 

I have made some modifications to the above formula:

test2 = 
VAR _CurrentIndex =
    FIRSTNONBLANK ('Table'[Index], 1 )
VAR _CurrentStatus =
    FIRSTNONBLANK ( 'Table'[State], 1 )
VAR _IndexOfPreviousCheckIN =
    CALCULATE (
        MAX ( 'Table'[Index] ),
        FILTER (
            ALL ( 'Table' ),
            AND ( 'Table'[Index] < _CurrentIndex, 'Table'[State] = "C/In" )
        ) //,OR('InOutData(PAK)'[Index] < CurrentIndex,
        // 'InOutData(PAK)'[State] = "C/Out")
    )
//*****************************************************************************************
var _lastOut=
        CALCULATE(
        LASTNONBLANK('Table'[Index],MAX('Table'[State])="C/Out"),
        FILTER(ALL('Table'),AND ( 'Table'[Index] < _CurrentIndex, 'Table'[State] = "C/Out" ))
    )
//*****************************************************************************************
VAR _IndexOfFollowingCheckOut =
    IF ( 
        ISBLANK ( _IndexOfPreviousCheckIN ), 
        0, 
        // _IndexOfPreviousCheckIN+1
//*****************************************************************************************
        _lastOut
//*****************************************************************************************
    )
var _result=
        IF (
        OR ( _CurrentIndex = 0, _CurrentStatus = "C/Out" ),
        0,
        DATEDIFF (
            CALCULATE (
                FIRSTNONBLANK ( 'Table'[Date & Time State], 0 ),
                FILTER (
                    ALL ( 'Table' ),
                    'Table'[Index] = _IndexOfFollowingCheckOut
                )
            ),
            FIRSTNONBLANK ( 'Table'[Date & Time State], 1 ),
            MINUTE
        )
    )
RETURN _result

and for more clarification i want difference between 

last_Out and First_In

Hi, @ziyabikram96 

To create a calculated column like this:

isIN_is0 =
VAR _previouIn =
    CALCULATE (
        MIN ( [Index] ),
        FILTER (
            ALL ( 'Table' ),
            [State] = "C/In"
                && [Index]
                    = EARLIER ( [Index] ) - 1
        )
    )
VAR _if =
    IF ( 'Table'[State] = "C/In", IF ( [Index] - _previouIn = 1, 1 ) )
RETURN
    _if

then the test3 would be like this:

test_3 = 
VAR _CurrentIndex =
    FIRSTNONBLANK ('Table'[Index], 1 )
VAR _CurrentStatus =
    FIRSTNONBLANK ( 'Table'[State], 1 )
VAR _IndexOfPreviousCheckIN =
    CALCULATE (
        MAX ( 'Table'[Index] ),
        FILTER (
            ALL ( 'Table' ),
            AND ( 'Table'[Index] < _CurrentIndex, 'Table'[State] = "C/In" )
        ) //,OR('InOutData(PAK)'[Index] < CurrentIndex,
        // 'InOutData(PAK)'[State] = "C/Out")
    )
//*****************************************************************************************
var _lastOut=
        CALCULATE(
        LASTNONBLANK('Table'[Index],MAX('Table'[State])="C/Out"),
        FILTER(ALL('Table'),AND ( 'Table'[Index] < _CurrentIndex, 'Table'[State] = "C/Out" ))
    )
//*****************************************************************************************
//*****************************************************************************************
var _firstIn=
    IF(MAX('Table'[State])="C/In",_lastOut+1)
//*****************************************************************************************
VAR _IndexOfFollowingCheckOut =
    IF ( 
        ISBLANK ( _IndexOfPreviousCheckIN ), 
        0, 
        // _IndexOfPreviousCheckIN+1
//*****************************************************************************************
        _lastOut
//*****************************************************************************************
    )
var _result=
        IF (
        OR(
//*****************************************************************************************
            OR ( _CurrentIndex = 0, _CurrentStatus = "C/Out" ),MAX('Table'[isIN_is0])=1),
//*****************************************************************************************
        0,
        DATEDIFF (
            CALCULATE (
                FIRSTNONBLANK ( 'Table'[Date & Time State], 0 ),
                FILTER (
                    ALL ( 'Table' ),
                    'Table'[Index] = _IndexOfFollowingCheckOut
                )
            ),
            // FIRSTNONBLANK ( 'Table'[Date & Time State], 1 ),
//*****************************************************************************************
            CALCULATE(
                MAX('Table'[Date & Time State]),
                FILTER(
                    ALL('Table'),
                    'Table'[Index]=_firstIn
                )
            ),
//*****************************************************************************************
            MINUTE
        )
    )
RETURN _result

Thanks for your time and kind responses I got my expected result 

[ziyabikram96]

Thanks for your time and response in C/Out logic is ok as it is highlited in yellow but the problem is occured in C/In as it is marked with black colour , I want minimum C/In and thier respective result and rest of it will return 0

@ziyabikram96 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/3395....
The basic pattern is:
Column = 
  VAR __Current = [Value]
  VAR __PreviousDate = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Date])

  VAR __Previous = MAXX(FILTER('Table',[Date]=__PreviousDate),[Value])
RETURN
  __Current - __Previous

Hi, Didn't get the expected result I tried your method but failed to to get it

[sm_talha]

Can you please show how are you calculating the time difference?

[ziyabikram96]

Here it is

test =

VAR CurrentIndex = FIRSTNONBLANK('InOutData(PAK)'[Index],1)

VAR CurrentStatus = FIRSTNONBLANK('InOutData(PAK)'[State],1)

VAR IndexOfPreviousCheckIN =

CALCULATE(

MAX('InOutData(PAK)'[Index]),

FILTER(

ALL('InOutData(PAK)'),

AND(

'InOutData(PAK)'[Index] < CurrentIndex ,

'InOutData(PAK)'[State] = "C/In"

)

)//,OR('InOutData(PAK)'[Index] < CurrentIndex,

// 'InOutData(PAK)'[State] = "C/Out")

)

VAR IndexOfFollowingCheckOut =

IF(

ISBLANK(IndexOfPreviousCheckIN),

0,

IndexOfPreviousCheckIN +1

)

RETURN

IF(

OR(CurrentIndex = 0, CurrentStatus = "C/Out" ),

0,

DATEDIFF(

CALCULATE(

FIRSTNONBLANK('InOutData(PAK)'[Time],0),

FILTER(

ALL('InOutData(PAK)'),

'InOutData(PAK)'[Index] = IndexOfFollowingCheckOut

)

),

FIRSTNONBLANK('InOutData(PAK)'[Time],1),

MINUTE

)

)
