@Anonymous Use MAXX to get the max of all the values and then use that to compare with the current value.

@Greg_Deckler how i can do that the maxx need a expresion wich is not resulting in what i want because i want whe max of my cumulative by the worker id by the week i need to apply the filter first 

this formula is giving me the correct number but is takin all values over 40 i just want the max value over 40

@Anonymous Like this:

Column =
  VAR __WorkerID = [worker id]
  VAR __Week = [week]
  VAR __Max = MAXX(FILTER('Table',[worker id] = __WorkerID && [week] = __Week),[Cumulative hours for week])
RETURN
  IF([Cumulative hours for week] = __Max,__Max - 40, BLANK())
