When usingImport Sets and Transform Mapsto ingest data into the CMDB, it is critical that records are processed through theIdentification and Reconciliation Engine (IRE)to prevent duplicates and enforce source precedence. InServiceNow, this is achieved by invoking the IREafterthe transform logic has completed.

TheonAftertransform script is the correct place to call the IRE API. At this stage, the transformed data has already been mapped and prepared, allowing the IRE to correctly identify whether a CI already exists and reconcile updates according to defined rules.

TheonBeforeandonStartscripts execute too early—before data mapping is complete—making them unsuitable for IRE processing. TheonCompletescript runs after the entire import job finishes and is not intended for per-record CI identification and reconciliation.

Because Import Sets can bypass IRE if not configured correctly, using anonAfter scriptis a critical Data Foundations safeguard when this ingestion method is chosen.

Therefore, the correct answer isC – onAfter.
