    Hi  yogeshk77 ,

     

    Here are the steps you can follow：

    1. Create calculated column.

    rank =
RANKX(
    FILTER(ALL(Expected),
    'Expected'[Team]=EARLIER('Expected'[Team])),[Reporting Sprint ID],,DESC)
    Sum of Six Period Average =
IF(
    [rank] <=6,
    AVERAGEX(
        FILTER(ALL('Expected'),
        'Expected'[Team]=EARLIER('Expected'[Team])&&
        'Expected'[rank]>=EARLIER('Expected'[rank])&&'Expected'[rank]<=EARLIER('Expected'[rank])+5),[Story_Points])

)

    2. Result:

yogeshk77 Should be:

Column = 
  VAR __Team = [Learnosity_Team_10202]
  VAR __Sprint = [Reporting Sprint ID]
  VAR __Sprints = SELECTCOLUMNS(FILTER('Table', [Learnosity_Team_10202] = __Team && [Reporting Sprint ID] <= __Sprint), "__SprintID", [Reporting Sprint ID])
  VAR __SprintsText = CONCATENATEX( __Sprints, [__SprintID], "|", [__SprintID], DESC)
  VAR __Table = 
    ADDCOLUMNS(
      GENERATESERIES( 1, COUNTROWS(__Sprints), 1 ),
      "__SprintID", PATHITEM(__SprintsText, [Value])
    )
  VAR __FinalSprints = FILTER(__Table, [Value] <= 6)
  VAR __Result = AVERAGEX( FILTER('Table', [Reporting Sprint ID] IN __FinalSprints), [Sum of Story_Points_10004)
RETURN
  __Result

Quite possible that you will get some kind of error complaining about text vs. number. Also, couldn't test this so the probability of a syntax error is fairly high. If you provide your sample data as text, could test this in a PBIX file and provide the PBIX file to you.
