AVERAGES Calculation Error in PowerPivot for Heirarchical Data

[memon_rehan]

Hello Friends,

I used the DAX Parent Child Hierarchy DAX Model from this link https://www.daxpatterns.com/parent-child-hierarchies/ to build my own Organization GOALS Heirarchical Data Model

In the measure formula as explained in the above link, I replaced the SUM with AVERAGE

Original Formula as per the above link

[Sales Amount Simple] :=

IF (

    [BrowseDepth] > [MaxNodeDepth],

    BLANK (),

    SUM ( Transactions[Amount] )

)

Changed Formula

[GoalsAchieved] :=

IF (

    [BrowseDepth] > [MaxNodeDepth],

    BLANK (),

    AVERAGE( ConsolidatedGoals[Actual] )

)

However the result is not exactly as per the required average.

Can someone help me with a solution

Hi @memon_rehan ,

It shows correct result. If you go back to source table and calculate it here

you see the same results as in PivotTable. That's since 3.6.4 has subitems and

AVERAGE(AVERAGE(range1)+AVERAGE(range2))  or
(range1/n1 + range2/n2)/2

is not equal to

AVERAGE(range1, range2)  or
(range1, range2)/(n1+n2)

Above is also in attached file

@Sergei Baklan Thanks for the quick reply. It might the correct for Microsoft Excel calculation, however I need the right percentage based on the selection. Is there anything i can do with the Measure formula to achieve this ?

@Sergei Baklan 

You are right but what i want is Average of only Levels below it and not everything below it.
