A lookup occurs during Verification. In IBM Datacap, verification is the point at which captured and recognized data is reviewed, corrected, validated, or enriched before the batch is exported to downstream systems. Lookup actions are typically used to validate field values against an external source, such as a database, REST service, SOAP service, or application-specific reference table. For example, an operator can enter partial known data in a verify task field, invoke a lookup, select the correct returned record, and populate or validate related fields. This pattern fits the verification phase because the operator is resolving uncertain or incomplete captured values while the document is still inside Datacap's quality-control workflow. Profiler is more associated with identifying or structuring documents, VScan is associated with scanning or virtual scanning ingestion, and Export is the final handoff after validation. Therefore, Verification is the precise task where interactive lookup behavior belongs.
