Computing rollup weighted sum

Seeking assistance from Power BI experts.   I'm trying to compute the overall progress of Program 1, which is sum of each individual Project Progress, based on the weightage assigned for each Proje...

    So based on your new requirement to apply the weightings differently at different levels you might be able to do something like the following which just dynamically changes the factor inside the SUMX based on which columns are filtered

     

    SUMX( table1, IF(ISFILTERED( table1[Project]), 1,  -- at the project level multiply by 1
        IF( ISFILTERED(Program], [Project Weightage],  -- at the program level apply the project weight
        [Program Weightage] * [Project Weightage])   -- at the total level apply program and project weighting
    * [Progress])

However, SUMX doesn't seem to resolve the problem. 

 

Mainly is because each level (Overall > Program > Project) has its own weightage. 

So this is additional information. We can really only answer based on the information you provided.

 

But doesn't the same approach still work? Isn't the program just an additional weighting that you need to apply?

 

eg.

SUMX(  <table name>, [Program Weightage] * [Project Weightage] * [Progress])

The computation of the Progess (%) should be dynamic based on which level is selected.

 

For eg:-
When selected Project A, Progress (%) = 4.8%
When selected Program 1, Progress (%)= = 0.94%
When selected Program 2, Progress (%) = 2.4%
When selected Overall Progress (Program 1 and Program 2), the Progresss (%) = 1.96%

 

I don't think in this case, SUMX( <table name>, [Program Weightage] * [Project Weightage] * [Progress]) works.
