When you create normalized output data, the data values do not repeat in an output group. You create a one-to-one relationship between the hierarchy levels in the SOAP message and the output groups of ports.
When the SOAP message contains a Departments parent hierarchy level and an Employees child hierarchy level, you might create the following groups of ports:
Departments
Department_Key
Department_ID
Department_Name
Employees
Department_Key
Employee_ID
Employee_Name
The Department_Key is a generated key that relates the Employees output group to a Department group.
