• What is the cause and solution for SAP error message WSS100 - HTTP status code: & status text & ?

  SAP Error Message:
  
  WSS100 HTTP status code: & status text &
  
  Cause
  This error message typically occurs in SAP systems when there is an issue with an HTTP(S) communication, often related to Web Services or HTTP calls made from SAP (e.g., via SOAMANAGER, HTTP destinations, or web service clients). The placeholders & indicate that the actual HTTP status code and status text are dynamically inserted at runtime.
  Common causes include:
  
  Network connectivity issues: The SAP system cannot reach the target HTTP endpoint.
  Incorrect URL or endpoint: The URL configured for the web service or HTTP call is wrong or unreachable.
  Authentication problems: Missing or incorrect credentials for the HTTP service.
  SSL/TLS issues: Problems with certificates or SSL handshake failures.
  Server-side errors: The remote HTTP server returns an error (e.g., 404 Not Found, 500 Internal Server Error).
  Proxy or firewall blocking: Network devices blocking the HTTP request.
  
  
  Solution
  
  
  Check the HTTP Status Code and Text:
  
  The actual status code and text (e.g., 404 Not Found, 401 Unauthorized) provide clues about the problem. Analyze the exact message to understand the failure.
  
  
  Verify the URL/Endpoint:  
  
  Confirm the URL is correct and accessible from the SAP server.
  Use tools like ping, telnet, or curl from the SAP server host to test connectivity.
  
  
  
  Check Network and Firewall Settings:  
  
  Ensure no firewall or proxy is blocking the request.
  If a proxy is used, verify proxy settings in SAP (SM59 HTTP destination or SOAMANAGER).
  
  
  
  Review Authentication Settings:  
  
  Confirm that the credentials (Basic Auth, OAuth, certificates) are correctly configured.
  Check if the remote service requires additional headers or tokens.
  
  
  
  SSL/TLS Configuration:  
  
  If HTTPS is used, verify that the SSL certificates are correctly imported into the SAP system’s STRUST.
  Check for SSL handshake errors in system logs.
  
  
  
  Check SAP Logs and Traces:  
  
  Use transaction SMICM to check HTTP traces.
  Use ST22 for dumps.
  Use SM59 test connection for HTTP destinations.
  Check application logs or SOAMANAGER for web service errors.
  
  
  
  Contact Remote Service Provider:  
  
  If the remote server returns an error, coordinate with the service provider to resolve server-side issues.

  Summary
  The WSS100 HTTP status code: & status text & error indicates a failure in HTTP communication with a remote service. The key to resolving it is to identify the actual HTTP status code and message, then troubleshoot connectivity, authentication, SSL, and configuration issues accordingly.
