Cumulative.......break down shift cumulative to hourly values

[moshea4]

Hi

My Oracle database is giving me the cumulative value for the production from a production line, I want to calculate the hourly values as I have done in the column "Hourly Values (I HAVE CALCULATED)" in excel

Each Shift ID has 12 hours and the value is the cumulative shift total, so hour 1 actual production should be the value given 16980 and hour 2 should be Hour 2 value - hour 1 value 31700-16980=14720

How to do this in powerBi

LINE_DESCR	SHIFT_ID	SHIFT_HOUR	VALUE	Hourly Values (I HAVE CALCULATED)

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...

I would go with the first one, just grab your current shift, subtract one, look that value up accounting for Shift Id, should be fairly simple.

Column =
  VAR __CurrentShift = [SHIFT_HOUR]
  VAR __CurrentValue = [VALUE]
  VAR __PreviousValue = 
    MAXX(
      FILTER(
        'Table',
        [LINE_DESCR] = EARLIER([LINE_DESCR]) &&
          [SHIFT_ID] = EARLIER([SHIFT_ID]) &&
            [SHIFT_HOUR] = __CurrentShift - 1
      ),
      [VALUE]
     )
RETURN
  __CurrentValue - __PreviousValue

Yes...I just had to add in a filter on Tag Name also. Thank you.
