When you connect transformations to a Router transformation in a mapping, consider the following rules:
You can connect one group to one transformation or target.
You can connect one output port in a group to multiple transformations or targets.
You can connect multiple output ports in one group to multiple transformations or targets.
You cannot connect more than one group to one target or a single input group transformation.
You can connect more than one group to a multiple input group transformation, except for Joiner transformations, when you connect each output group to a different input group.
