Key Generator Output Ports
The Key Generator transformation output ports create IDs and group keys that the Match transformation uses to process records.
The following table describes the output ports for the Key Generator transformation:
Property | Description |
|---|
SequenceID | Creates an ID that identifies each record in the source data set. |
GroupKey | Creates the group keys that the Match transformation uses to process records. |
When you create a reusable Key Generator transformation, use the Overview view to view the ports. When you add a nonreusable transformation to a mapping, use the Ports tab of the Properties view to view the ports.
