• What is the cause and solution for SAP error message SPRX129 - The selected WSDL does not describe the selected proxy object ?

  The SAP error message SPRX129, which states "The selected WSDL does not describe the selected proxy object," typically occurs when there is a mismatch between the Web Service Description Language (WSDL) file and the proxy object that you are trying to use in your SAP system. This can happen for several reasons, including changes in the WSDL, incorrect configuration, or issues with the proxy generation.
  Causes:
  
  WSDL Mismatch: The WSDL file you are using does not match the structure or the expected operations of the proxy object in SAP.
  Proxy Object Not Generated: The proxy object may not have been generated correctly or is outdated compared to the WSDL.
  Changes in the Service: If the web service has been updated (e.g., new operations added, existing operations modified), the WSDL may have changed, leading to a mismatch.
  Incorrect WSDL URL: The URL provided for the WSDL might be incorrect or pointing to an outdated version.
  Namespace Issues: The namespaces defined in the WSDL may not match those expected by the proxy object.
  
  Solutions:
  
  
  Regenerate the Proxy Object:
  
  Go to the SAP transaction code SPROXY.
  Find the relevant proxy object and regenerate it using the updated WSDL.
  Ensure that you are using the correct WSDL URL.
  
  
  
  Verify WSDL:
  
  Check the WSDL file to ensure it is correct and contains the expected operations and data types.
  Compare the WSDL with the proxy object to identify any discrepancies.
  
  
  
  Update the WSDL:
  
  If the WSDL has changed, make sure to update the proxy in SAP to reflect these changes.
  You can do this by importing the new WSDL into the SAP system.
  
  
  
  Check Namespaces:
  
  Ensure that the namespaces in the WSDL match those expected by the proxy object.
  If there are discrepancies, you may need to adjust the WSDL or the proxy configuration.
  
  
  
  Test the Web Service:
  
  Use tools like SOAP UI or Postman to test the web service independently of SAP to ensure it is functioning correctly and returning the expected responses.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific version of the software you are using, as there may be known issues or additional steps required.
  
  
  
  Related Information:
