Cross-key rules the schema cannot express: a duplicate_key component this source's field map does not fill is refused, because a key over an always-empty field makes every row a duplicate of every other; a source bound to an aggregator connection (reserved key connection_config_name) cannot carry a duplicate_key of its own, and a config holding both is refused in either direction; and editing duplicate_key governs later imports only — rows already imported keep the key they were deduplicated under, so a duplicate straddling the change is knowingly not detected. properties: blank_external_id: description: >- What happens to a row whose mapped external id is blank. REJECT (the default when the key is absent) fails the row. NEEDS_REVIEW imports it under a synthetic reference with status PENDING_REVIEW, so a blank reference becomes a reviewable import instead of an import failure. enum: - REJECT - NEEDS_REVIEW type: string camt053: additionalProperties: false description: >- How this source's camt.053 files map onto the canonical fields.

The moment duplicate-key detection last changed meaning on this source, either because duplicate_key was edited or because the field map remapped the column a declared component reads.

A value sent by a client is discarded. format: date-time readOnly: true type: string duplicate_policy: description: >- What happens to a row that repeats this source's duplicate key. FLAG_AS_EXCEPTION (the default when the key is absent) keeps the repeat out of the import and raises a duplicate exception on the row it repeated. KEEP_FIRST drops the repeat and raises nothing, so a collision leaves no trace anyone can act on. REJECT counts the repeat as an import error. enum: - FLAG_AS_EXCEPTION - KEEP_FIRST - REJECT type: string fail_on_error_rate_percent: description: >- Fail the whole import when the percentage of failed rows exceeds this whole number.
