Query Resources Exceeded Error ABC classification

[kianhaw98]

Hi Community,

I’m building an Item Weightage Analysis table in Power BI.

I want to add a new measure which is:
Accumulated Share % (12M) → cumulative sum of “Share % Sales Value per Item (12M)” in descending order of sales within each Cat1.

Example for FE CYLINDER:

• 36.24% → 36.24%

  • 8.33% → 44.57%

  • 7.02% → 51.59%
    … and so on. 

I tried measure using RANKX + TOPN + SUMX. It works, but on 100k+ items I get “Query has exceeded available resources”. Next, I intended to calculate a new measure which returns A for those items having cumulative % less than 80%, B for which between 80% to 95% and C for which between 95% to 100%.

What’s the best practice to calculate this cumulative % by category at scale?Any guidance, optimized DAX, or advice on whether to pre-aggregate this in the data source would be really helpful🙏

SQLBI have a pattern for ABC analysis which you can read about at https://www.daxpatterns.com/abc-classification/ .

They also have a library of functions, using the new user defined functions in public preview in the September 2025 update, which you can find at https://daxlib.org/package/DaxPatterns.AbcClassification/ .

Maybe its exceeding 225 seonds limitation set by PBI desktop.
so try creating reusable measures and try to call them in the calculations. this would reduce  the time significantly
