TOPN without a tie-breaker
"TOPN without a tie-breaker" is one of the dax quality checks Auditabi runs on a Power BI semantic model. n measure(s) use TOPN with a single order-by column. It is a low-severity finding: hygiene and maintainability, worth fixing when you next touch the object. Add a second order-by column as a tie-breaker, or accept and document the ties.
What is detected
n measure(s) use TOPN with a single order-by column. When several rows share the same value the engine returns all of them, so a "top 5" can show seven rows.
Why it matters
Hygiene and maintainability. Fix when touching the object.
How to fix it
Add a second order-by column as a tie-breaker, or accept and document the ties.
