When you use the Create SOAP Integration wizard to generate the SOAP connector, it populates the contents of the Web service’s WSDL file on the WSDL tab. This information is for reference and is read-only. For example, you can use this information to understand how the connector was created.
If the information was generated by uploading a WSDL file, the WSDL URL section is blank.
To make changes in the WSDL file, you need to run the wizard with the updated information.
