SPRX046 - Details

• The SAP error message SPRX046, which states "Proxy generation terminated: Message must have exactly one part," typically occurs during the generation of a proxy object in SAP when the message structure defined in the Web Service or the Enterprise Services is not correctly configured. This error indicates that the message being processed has more than one part or is not structured as expected.
  
  Cause:
  
  Multiple Parts in Message: The most common cause of this error is that the message definition in the WSDL (Web Services Description Language) file has multiple parts, but the proxy generation process expects exactly one part.
  Incorrect WSDL Configuration: The WSDL might be incorrectly defined, leading to ambiguity in the message structure.
  Service Interface Definition: The service interface in SAP might not be properly defined, leading to issues during proxy generation.
  
  
  Solution:
  
  Check WSDL Definition: Review the WSDL file associated with the service. Ensure that the message definitions have only one part.
