Iterator over a large table

What this rule checks

A DAX iterator evaluates row by row over a large table.

Everscope evaluates only the metadata needed for this deterministic check. It does not read dataset rows or values.

Why this is a risk

Large iterator workloads can create high Formula Engine cost and slow report interactions.

In a governed environment this can weaken traceability, operational reliability, or the evidence available to reviewers and auditors.

How to resolve it

1. Measure the query plan and replace row iteration with a validated aggregation where equivalent.
2. Validate the change with the accountable owner, rerun the same metadata scan, and retain the before-and-after evidence.
