ALL-DATA0002 · missing_data_field_reference

Count referenced fields absent from an existing data asset schema.

This is a deterministic rule for all languages. Read its implementation.

Definition

Resolve every field one source location reads against the schema the catalog holds for the asset that field belongs to, and report a field the schema does not declare. This is the defect a type checker cannot see, because the schema lives in the warehouse and the reference is a string, so the first evidence of a renamed column is usually a job that failed overnight.

An asset the catalog does not hold at all is excluded and left to ALL-DATA0001, so one renamed table produces one finding rather than one for every column somebody read from it.
