• What is the cause and solution for SAP error message SRT_WSP2285 - Invalid WSDL flavour code: Incorrect SOAP style ?

  The SAP error message SRT_WSP2285 indicates that there is an issue with the Web Service Description Language (WSDL) file being used in your SAP system. Specifically, the error message states that there is an "Invalid WSDL flavour code" due to an "Incorrect SOAP style." This typically occurs when the WSDL file does not conform to the expected SOAP style (RPC or Document) that the SAP system is configured to handle.
  Cause:
  
  WSDL Configuration: The WSDL file may be incorrectly configured. It might be using a SOAP style that is not supported by the SAP system (e.g., using RPC when Document is expected, or vice versa).
  Service Implementation: The web service being consumed may not be implemented correctly, leading to a mismatch between the expected and actual WSDL.
  SAP Configuration: The SAP system may not be set up to handle the specific SOAP style defined in the WSDL.
  
  Solution:
  
  
  Check WSDL File: Review the WSDL file to ensure that it is correctly defined. Look for the soap:binding element and check the style attribute. It should be either rpc or document, depending on what your SAP system expects.
  
  If the SAP system expects a document style, ensure that the WSDL specifies style="document".
  If it expects rpc, ensure that it specifies style="rpc".
  
  
  
  Modify WSDL: If you have control over the WSDL, modify it to match the expected SOAP style. If you do not have control over the WSDL, you may need to contact the service provider to request a corrected version.
  
  
  SAP Configuration: Check the configuration settings in your SAP system related to web services. Ensure that the settings align with the SOAP style defined in the WSDL.
  
  
  Testing: After making changes, test the web service again to see if the error persists. Use tools like SOAP UI or Postman to validate the WSDL and the service response.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for additional guidance on handling WSDL and SOAP style issues.
  
  
  Related Information:
  
  
  SOAP Styles: Understand the difference between RPC and Document styles:
  
  RPC (Remote Procedure Call): This style is used for calling a specific function or procedure on the server.
  Document: This style is used for exchanging documents, where the message structure is defined in the WSDL.
  
  
  
  SAP PI/PO: If you are using SAP Process Integration (PI) or Process Orchestration (PO), ensure that the integration scenarios are correctly configured to handle the WSDL and SOAP styles.
  
  
  Error Logs: Check the SAP error logs for additional details that may provide more context about the error.
  
  
  By following these steps, you should be able to resolve the SRT_WSP2285 error and successfully consume the web service.
