The transformation includes preset ports that identify the records in each matched pair. The preset port names are

RowId

and

RowId1

. Each row ID value identifies a record in the output data.

The row ID values correspond to the ports that you select in a match strategy. When you configure a strategy, you select port names with the suffix _1 or _2. The RowId value identifies the record that contains a port with the suffix _1. The RowId1 value identifies the record that contains a port the suffix _2.

You can use other output ports to review the relationships between the records. The link port values and driver port values indicate the extent of the similarity between the records in each cluster.

In the current example, you connect all the ports to the data target. To view the output data on the ports, run the Data Viewer.
