Days between dates of same column using DAX

Hi All,

I have a requirement to find the days between dates of the same column. 
The first value should be the difference between the date and the date of the next step and the last value should be zero.

I have attached a sample pbix file with date here. 
Could someone please suggest on how to achieve this using DAX.

    Hi POSPOS ,

    Please try:

    Column = 
VAR _cur_protocol = 'export'[Protocol Number]
VAR _cur_index = 'export'[Index]
VAR _next_index = CALCULATE(MIN('export'[Index]),FILTER(ALL('export'),'export'[Protocol Number]=_cur_protocol && 'export'[Index]>_cur_index))
VAR _next_date = CALCULATE(MIN('export'[Status Date]),ALLEXCEPT('export','export'[Index]),'export'[Index]=_next_index)
VAR _result = COALESCE(DATEDIFF('export'[Status Date],_next_date,DAY),0)
RETURN
_result

    DaysTillNextSatus=
    VAR CurrentStatusDate = Min('export'[Status Date])
    VAR CurrentProtocol = SELECTEDVALUE('export'[Protocol Number])
    var NextDate = CALCULATE(
        Min('export'[Status Date]),
        FILTER(
            ALL('export'),
            'export'[Status Date] > CurrentStatusDate && CurrentProtocol = 'export'[Protocol Number]
        )
    )
    VAR vDifference = DATEDIFF(CurrentStatusDate , NextDate, DAY)

    RETURN if(ISBLANK(vDifference), 0, vDifference)

      Data-estDog  - thank for the response.

      When the dates are same, the values are not showing as expected. In this example, "Staff" comes before "Assigning", hence staff should be 9 and Assigning should be 0.

      But 9 is repeated for both the statuses.

        You would need a more granular date/time stamp. Or a sequence number (order the status was changed in) in order to achieve that.
