Date difference between dates in same column

Hi Greg_Deckler 

i have used a slightly different formula, but your pattern works well:

Difference = 
VAR _CurrentDate = 'Table'[Extra_Fields.Log_MS_Date_Started]
VAR _PreviousDate = 
    MAXX(
        FILTER(
            'Table',
            'Table'[Extra_Fields.Log_MS_Date_Started] < EARLIER('Table'[Extra_Fields.Log_MS_Date_Started])
        ),
        'Table'[Extra_Fields.Log_MS_Date_Started]
    )
RETURN
   IF(_PreviousDate = BLANK(), 0, _CurrentDate - _PreviousDate)

cpereyra - If I had to guess, you are probably not including all of the filtering criteria that you need to. Like whatever that field is just to the left of your date field. Your filter criteria needs to include all of the row columns that you want to "group" together.

So, like:

FILTER(
  'Table',
  [Column] = EARLIER([Column]) &&
  [Column1] = EARLIER([Column1])
)
