You can generate a web service mapping by importing the web service source or target from a WSDL that you can access locally or through a URL.
When you generate a web service mapping by importing source and target definitions from a WSDL, the Designer creates the source definition from the input message of the operation you select. It creates the target definition from the output message of the operation you select.
The web service mapping generated from a WSDL contains the following objects:
Web service source definition
Source qualifier
Web service target definition
The Designer links the ports from the source instance through the target instance. To complete the mapping, add the transformations and other mapping component necessary for the web service you want to create.
To generate a mapping from a WSDL:
In the PowerCenter Designer, open the Mapping Designer.
Click Mappings > Create Web Service Mappings > Import from WSDL.
The procedure to generate a web service mapping by importing sources and targets from a WSDL is the same as the procedure to create web service sources or target definitions from a WSDL. For more information, see Importing a Web Service Source or Target Definition.
