Duplicate Record Exception Transformation Output Ports

The Duplicate Record Exception transformation has multiple output groups. By default, the transformation writes duplicate records to the

Standard Output

group. The transformation writes potential matches to the

Cluster Data

group. You can add an output group for unique records.

You can change the record types that the transformation writes to output ports by changing the default settings on the

Configuration

view.

The following table describes the output ports for the

Standard Output

group:

Port	Description
Score	Decimal value between 0 and 1. Identifies the degree of similarity between the record and another record in a cluster.
Row_Identifier	A unique identifier for the record.
Cluster_ID	ID of the cluster that the Match transformation assigned the record to.
User-defined ports	The source data fields.

The following table describes the output ports in the

Cluster Data

group:

Port	Description
Row_Identifier	The unique identifier for the record.
Sequential_Cluster_ID	Identifies the cluster in a Human task. A workflow uses the sequential cluster ID to assign a cluster to an instance of a Human task.
Cluster_ID	Identifies the cluster that the record belongs to. The Match transformation assigns a cluster ID to all records.
Score	Decimal value from 0 to 1. Identifies the degree of similarity with the record that linked the record to the cluster.
Is_Master	String value that indicates if the record is the preferred record in the cluster. By default, the first row in the cluster is the preferred record. Value is Y or N.
Workflow_ID	ID that identifies the workflow for the record in a task. When you run the mapping outside of a workflow, the workflow ID is DummyWorkflowID.
User-defined ports	The source data ports.
