Text compared with UPPER or LOWER on both sides
"Text compared with UPPER or LOWER on both sides" is one of the reliability checks Auditabi runs on a Power BI semantic model. n expression(s) normalise case before comparing text. It is a low-severity finding: hygiene and maintainability, worth fixing when you next touch the object. Compare directly; use EXACT when a case-sensitive comparison is what you need.
What is detected
n expression(s) normalise case before comparing text. DAX comparisons are already case-insensitive, so the calls cost time and hide that fact from the reader.
Why it matters
Hygiene and maintainability. Fix when touching the object.
How to fix it
Compare directly; use EXACT when a case-sensitive comparison is what you need.
