Hi TFRec
lbendlin already provided a very good approach, but still, if you seeking another way of doing that you can check this video this is not exact but with some modification this might help you to attain solution: https://youtu.be/cs2AwJljBrQ?si=yQR7T5WZZMfTaSDh

Hello lbendlin ,
Thank you for the help. I have uploaded a pbix using publicly available trade data to replicate the issue at https://we.tl/t-KFNe32hvK9? (hope it is all right to give a WeTransfer link, it was mentioned on the upload data link as one of the ok mediums).
You will see there that for code "27090090" under partner country "NL" it only shows "BE" and "DE", but it should also show "ES" as they are the third biggest declarant country with 191 Million EUR for the code and partner country in question.
Edit: I initially accidentally replied to topic first.

on the top two levels do you want to show the total level value or only the value contributed by the underlying top 3?
Hello lbendlin ,
Thank you very much for having taken the time to look into this. Looking to have the value contributed by the underlying top 3, as it is working in your approach. Am however struggling to change the formula in such a way that it still does the top 3 for the other two upper levels as well.- lbendlin
You will have to create three calculated tables, either materialized or as part of the measure (there might be severe performance issues in the latter approach, especially with your amount of data). You need to start from the lowest level as I showed, and then need to use the result of that for the next level, and then the result of that for the top level.
Certainly doable but rather complex. Think about softening your requirement, or finding a graphical solution instead (like a decomposition tree)
