• What is the cause and solution for SAP error message SRT_WSP2296 - Invalid WSDL flavour code: Incorrect SOAP version ?

  The SAP error message SRT_WSP2296 indicates that there is an issue with the Web Service Description Language (WSDL) file being used in a SOAP web service call. Specifically, the error message "Invalid WSDL flavour code: Incorrect SOAP version" suggests that there is a mismatch between the expected SOAP version and the version specified in the WSDL.
  Cause:
  
  WSDL Version Mismatch: The WSDL file may be specifying a SOAP version (e.g., SOAP 1.1 or SOAP 1.2) that is not compatible with what the SAP system is configured to use.
  Incorrect Configuration: The service consumer or provider may be configured to use a different SOAP version than what is defined in the WSDL.
  WSDL File Issues: The WSDL file itself may be malformed or incorrectly defined, leading to the SAP system being unable to interpret it correctly.
  
  Solution:
  
  
  Check WSDL File: Review the WSDL file to ensure that it correctly specifies the SOAP version. Look for the soap:binding element and verify that it matches the expected SOAP version.
  
  For SOAP 1.1, it should look like:
  <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
  
  For SOAP 1.2, it should look like:
  <soap12:binding style="document" transport="http://www.w3.org/2003/05/soap-binds/http"/>
  
  
  
  
  Adjust SAP Configuration: If the WSDL is correct, check the configuration in the SAP system to ensure it is set to use the correct SOAP version. This can typically be done in the service consumer settings or in the service definition.
  
  
  Regenerate Service Proxy: If you have made changes to the WSDL or the service configuration, you may need to regenerate the service proxy in SAP to ensure that it picks up the latest changes.
  
  
  Test with Different SOAP Versions: If possible, test the web service with both SOAP 1.1 and SOAP 1.2 to determine which version is supported and functioning correctly.
  
  
  Consult Documentation: Refer to SAP documentation or the documentation of the web service you are trying to consume for any specific requirements regarding SOAP versions.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Web Service Testing Tools: Use tools like SoapUI or Postman to test the web service independently of SAP to verify that it is functioning correctly and to see the expected SOAP version.
  Logs and Traces: Enable logging or tracing in SAP to gather more detailed information about the error, which can help in diagnosing the issue further.
  
  By following these steps, you should be able to identify and resolve the issue related to the SRT_WSP2296 error message in SAP.
