  Service Configuration Issues: The web service might not be properly configured in the SAP system. This includes issues with the service endpoint, WSDL, or the mapping of the parameters.
  
  
  Versioning Issues: If there are multiple versions of the web service, the client might be calling an outdated version that does not support the parameters being sent.
  
  
  Data Type Issues: The data types of the parameters being sent may not match the expected data types defined in the web service.
