    Hello,

    I found the solution that I wanted. I post her in case can be useful for someonelse.

    I created a misure VALUE BIS

    VALUES BIS =

    VAR CURRENT_ROW=SELECTEDVALUE(TABLE[ID])

    VAR ROW3=CALCULATE(SUM(VALUE),FILTER(ALL(TABLE),TABLE[ID]=1))-CALCULATE(SUM(VALUE),FILTER(ALL(TABLE),TABLE[ID]=2))

    RETURN
    SWITCH(CURRENT_ROW,3,ROW3,SUM(VALUE))

     

    Best regards

jgreutert - Not sure you can really do that (replace the NULL with some value) if this is in an actual table. You could create a new column. 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/339586.
The basic pattern is:
Column = 
  VAR __Current = [Value]
  VAR __Previous = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Value])
RETURN
  __Current - __Previous
