• What is the cause and solution for SAP error message SRT_WSP898 - SOAP version is only allowed for endpoint WSDLs ?

  The SAP error message SRT_WSP898 indicates that there is an issue with the SOAP version being used in the context of a web service endpoint. This error typically arises when the SOAP version specified in the WSDL (Web Services Description Language) file does not match the expected version for the endpoint being accessed.
  Cause:
  
  Mismatched SOAP Versions: The error occurs when the SOAP version in the request does not match the version expected by the web service. For example, if the service is expecting SOAP 1.1 but the request is using SOAP 1.2, this error may be triggered.
  Incorrect WSDL Configuration: The WSDL file may be incorrectly configured to specify a SOAP version that is not supported by the endpoint.
  Service Configuration Issues: The service may be configured to only accept requests in a specific SOAP version, and the client is not adhering to that requirement.
  
  Solution:
  
  Check SOAP Version: Ensure that the SOAP version used in your request matches the version specified in the WSDL. You can do this by examining the WSDL file and confirming the SOAP binding.
  Update Client Configuration: If you are using a client application to call the web service, make sure that it is configured to use the correct SOAP version. This may involve changing settings in the client code or configuration files.
  Modify WSDL: If you have control over the WSDL, you may need to modify it to ensure that it correctly specifies the supported SOAP versions. This may involve creating separate WSDLs for different SOAP versions if necessary.
  Test with Different Tools: Use tools like SOAP UI or Postman to test the web service with different SOAP versions to see if the issue persists. This can help isolate whether the problem is with the client or the service itself.
  
  Related Information:
  
  SOAP Versions: SOAP 1.1 and SOAP 1.2 are the two main versions of the SOAP protocol. They have different specifications and may not be compatible with each other.
  WSDL Structure: A WSDL file defines the web service, including the operations, messages, and bindings. Understanding its structure can help in troubleshooting issues related to service calls.
  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 expected SOAP versions.
  
  By following these steps, you should be able to resolve the SRT_WSP898 error and successfully connect to the web service.
