A Router transformation has input ports and output ports. Input ports are in the input group, and output ports are in the output groups.
You can create input ports by copying them from another transformation or by manually creating them on the
Ports
tab.
The Developer tool creates output ports by copying the following properties from the input ports:
Port name
Datatype
Precision
Scale
Default value
When you make changes to the input ports, the Developer tool updates the output ports to reflect these changes. You cannot edit or delete output ports.
The Developer tool creates output port names based on the input port names. For each input port, the Developer tool creates a corresponding output port in each output group.
