Public Everscope rule
Many iterators in one measure
A measure contains several iterator functions in one expression.
What this rule checks
A measure contains several iterator functions in one expression.
Everscope evaluates only the metadata needed for this deterministic check. It does not read dataset rows or values.
Why this is a risk
Nested row-by-row evaluation can create substantial Formula Engine work at query time.
In a governed environment this can weaken traceability, operational reliability, or the evidence available to reviewers and auditors.
How to resolve it
- Measure the query plan and simplify nested iterators or introduce validated aggregations.
- Validate the change with the accountable owner, rerun the same metadata scan, and retain the before-and-after evidence.
