• What is the cause and solution for SAP error message SRT_CORE145 - Invalid SOAP Version ?

  The SAP error message SRT_CORE145: Invalid SOAP Version typically occurs when there is a mismatch between the expected SOAP version in the SAP system and the version being used by the client or service that is making the request. This error is commonly encountered in scenarios involving web services, particularly when using SAP's web service runtime (SRT).
  Cause:
  
  SOAP Version Mismatch: The most common cause is that the client is sending a SOAP message that does not conform to the expected SOAP version (e.g., SOAP 1.1 vs. SOAP 1.2).
  Incorrect Configuration: The web service might be configured to expect a specific SOAP version, and the incoming request does not match this configuration.
  Faulty Client Implementation: The client application may be incorrectly implemented, leading to the generation of an invalid SOAP envelope.
  Network Issues: Sometimes, network intermediaries (like proxies) can alter the SOAP message, leading to version mismatches.
  
  Solution:
  
  Check SOAP Version: Ensure that the client is using the correct SOAP version that the SAP service expects. If the SAP service is configured for SOAP 1.1, the client should send requests in that format, and similarly for SOAP 1.2.
  Review Service Configuration: In the SAP system, check the configuration of the web service to confirm which SOAP version it is set to accept. This can usually be found in the service definition or WSDL.
  Validate SOAP Envelope: Use tools like SOAP UI or Postman to validate the SOAP envelope being sent by the client. Ensure that it adheres to the expected structure and version.
  Update Client Code: If the client is custom-built, review the code to ensure it constructs the SOAP envelope correctly according to the expected version.
  Check for Intermediaries: If there are any proxies or middleware involved, ensure they are not altering the SOAP message in a way that changes the version or structure.
  
  Related Information:
  
  SOAP Versions: SOAP 1.1 and SOAP 1.2 have different specifications and structures. Ensure that the client and server are aligned on which version to use.
  WSDL: The Web Services Description Language (WSDL) file can provide insights into the expected SOAP version and operations.
  SAP Notes: Check SAP Notes for any known issues or patches related to the SRT and SOAP handling.
  Logging and Tracing: Enable logging in the SAP system to capture detailed error messages and request/response payloads for further analysis.
  
  By addressing the above points, you should be able to resolve the SRT_CORE145 error and ensure proper communication between the client and the SAP web service.
