Top N from the column

Issue I haveIssue I haveHi Experts,

Test Data file: PowerBi.Pbix 

I have data where the all reasons are in one column and I need to find the TOP 10 along with other columns where I need top 10, SD, mean etc, Reason count by Reason ( is the index created grouped by Reason). 

I tried following adapted from the solution in the Community Forum.  

1. I need help to get TOP 5 reasons in the column and

2. When I do not have to create the index in the query too, if possible so other measures can be done without adding the steps of Index and group by. 

 

 

RankReason = 
IF (
    ISINSCOPE ( 'Data'[ReasonCountByReason]),
    RANKX (
        CALCULATETABLE (
            VALUES ( Data[ReasonCountByReason] ),
            ALLSELECTED ( Data[ReasonCountByReason] )
        ),
        [ReasonCountByReason]
    ),
    IF (
        ISINSCOPE ( 'Data'[ReasonCountByReason] ),
        VAR TotalReasons = Data[TopReasons]
        RETURN
            CALCULATE (
                RANKX (
                    VALUES ( 'Data'[ReasonCountByReason] ),
                    [TopReasons],
                    Data[TopReasons]
                ),
                ALLSELECTED ()
            )
    )
)

Hi, @Anonymous 

 

Please try the following methods. You can solve it directly with Dax without creating indexes in the power query.

Measure:

Count name =
CALCULATE (
    COUNT ( Data[TotalReasons.Name] ),
    FILTER (
        ALL ( Data ),
        [TotalReasons.Name] = SELECTEDVALUE ( Data[TotalReasons.Name] )
    )
)
Count reason =
CALCULATE (
    COUNT ( Data[Reason] ),
    FILTER ( ALL ( Data ), [Reason] = SELECTEDVALUE ( Data[Reason] ) )
)

Rank name = RANKX(ALLSELECTED(Data[TotalReasons.Name]),[Count name],,DESC)
Top name = IF([Rank name]<=2,1,0)

Put the measure of Top name into the name's view and set it equal to 1.

Is this the result you want for Top 2 name?

 

Rank reason = RANKX(ALLSELECTED(Data[Reason]),[Count reason],,DESC)
Top reason = IF([Rank reason]<=5,1,0)

Is this the result you want for Top 5 reason?
