Dynamic Top N Ranking with Bucket-Based Filter Context
Hi Julia2023 ,
I was able to reproduce the scenario successfully using a sample dataset, and the ranking/filtering worked correctly with the shared approach.
I have attached a sample PBIX file for reference so you can compare the implementation with your current model/setup.
If the issue still exists, please share the following details -
sample data/model structure

Thank you.
Hi Julia2023 ,
The issue occurs because the ranking is being calculated across the entire dataset instead of within each bucket context.
To fix this, you need to explicitly preserve the bucket context while ranking.
You can achieve this by modifying the "RANKX" measure as follows:
Rank Within Bucket =
VAR CurrentBucket = MAX(Data[Bucket])
RETURN
RANKX(
FILTER(
ALL(Data),
Data[Bucket] = CurrentBucket
),
[Total Value],
,
DESC,
DENSE
)
Then create a Top N flag measure -
Top N Flag =
VAR N = SELECTEDVALUE('TopN Table'[N], 2)
RETURN
IF([Rank Within Bucket] <= N, 1, 0)
Finally, apply this measure as a visual level filter set to 1. This ensures Top N is evaluated within each bucket instead of globally.
Thank you.
