You can configure pass-through ports to any Data Processor transformation. Pass-through ports are input and output ports that receive input data and return the same data to a mapping without changing it.
You can configure pass-through ports in a Data Processor transformation instance that is in a mapping.
To add a pass-through port, drag a port from another transformation in the mapping. You can also add ports in the
Ports
tab of the
Properties
view. Click
New
to add a pass-through port.
When you add pass-through ports to a Data Processor transformation with relational input and hierarchical output, add the ports to the root group of the relational structure.
Data Processor transformations can include pass-through ports with custom data types.
