## Conditional Rolling Average

I have below mentioned Power BI table structure Table

WeightedVel table contains below columns

“Team_10202” as a String Data type

“Reporting Sprint ID” as an Integer Data type

“Story_Points_10004” as a Decimal Data type

Now, I need a calculated column in this table to get average of last six “Story_Points_10004”, ordered by “Reporting Sprint ID”, grouped by “Team_10202”
Ensure you include the value of the current row in this calculation

For e.g. if the data is like this ->

The output should be like this ->

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:

Thank you.. In the stand alone test PBI this works, but in practical I have multiple other teams and looks like due to that combination the rank function is not working as expected.

Here's the result from my actual PBI

You can check this file

I Need a calculated column in the table called "Data", which shows the output in the below table called "Expected Output"

@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 =
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.
