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 Designer creates output ports by copying the following properties from the input ports:
When you make changes to the input ports, the Designer updates the output ports to reflect these changes. You cannot edit or delete output ports. The output ports display in the Normal view of the Router transformation.
The Designer creates output port names based on the input port names. For each input port, the Designer creates a corresponding output port in each output group.
