When you view the transformation ports, show the ports if you do not need to view the operation hierarchy. When you show the ports, you can define groups, define ports, and map nodes from the operation output to the output ports.
The following figure shows the ports for a non-reusable Web Service Consumer transformation:
A Web Service Consumer transformation can have multiple input groups and multiple output groups. When you create ports, create groups and add the ports to the groups. Define the ports in a group hierarchy based on the structure of the operation input or operation output hierarchy. Add a key to relate a child group to a parent group. All groups except the lowest group in the hierarchy must have primary keys. All groups in the hierarchy except the root group must have foreign keys.
The transformation has a root input group named RequestInput. You must add a primary key to the root input group. The key must be string, bigint, or integer.
You can add additional pass-through ports to the root input group. Pass-through ports pass data through the transformation without modifying the data. The pass-through port can occur one time in the input data. You can add the pass-through port to any output group. Associate the output port to the input port. The input value that you pass through a SOAP request repeats in the output rows from the SOAP response.
You can also add HTTP headers, cookie ports, a dynamic URL port, and ports for web service security authentication to the root input group. Data in the root group occurs one time.
To map an operation output node to an output port, click the field in the
Location
column and expand the hierarchy in the
Select Location
dialog box. Then, choose a node from the hierarchy.
