  Text:
  
  Error when adjusting the service end point '&1' for WS Security logon
  
  Cause
  This error occurs during the configuration or runtime of Web Service Security (WS-Security) in SAP, specifically when the system tries to adjust or set the service endpoint URL for WS-Security logon but fails.
  Common causes include:
  
  Incorrect or missing service endpoint URL: The endpoint URL provided for the WS-Security logon service is invalid, not reachable, or incorrectly configured.
  Network or connectivity issues: The SAP system cannot reach the specified endpoint due to network problems, firewall restrictions, or proxy issues.
  Configuration inconsistencies: The WS-Security settings in the SAP system (such as in SOAMANAGER or related configuration transactions) are incomplete or inconsistent.
  Authorization or certificate issues: The system might lack the necessary authorizations or the SSL certificates required to establish a secure connection to the endpoint.
  Transport or protocol mismatch: The endpoint expects a different protocol or security standard than what is configured in SAP.
  
  
  Solution
  To resolve the WSS206 error, follow these steps:
  
  
  Verify the Service Endpoint URL:
  
  Check the endpoint URL configured for the WS-Security logon service.
  Ensure the URL is correct, reachable, and uses the correct protocol (HTTP/HTTPS).
  Test the endpoint URL externally (e.g., via a browser or curl) to confirm accessibility.
  
  
  
  Check Network Connectivity:
  
  Ensure the SAP server can reach the endpoint URL.
  Verify firewall rules, proxy settings, and network routes.
  If a proxy is used, confirm proxy settings are correctly configured in SAP.
  
  
  
  Review WS-Security Configuration:
  
  Use transaction SOAMANAGER to review the web service configuration.
  Check the binding and endpoint settings for the WS-Security logon service.
  Ensure that the service endpoint is correctly maintained and active.
  
  
  
  Check SSL and Certificates:
  
  If HTTPS is used, verify that the SSL certificates are correctly installed and trusted by the SAP system.
  Use transaction STRUST to manage and check certificates.
  Ensure that the SSL handshake can be completed successfully.
  
  
  
  Check Authorizations:
  
  Verify that the user or service account running the WS-Security logon has the necessary authorizations.
  Check roles and profiles assigned.
  
  
  
  Review Logs and Traces:
  
  Check the SAP system logs (SM21), developer traces (ST11), and HTTP logs for more detailed error information.
  Enable trace for WS-Security if needed to get more insight.
  
  
  
  Adjust or Recreate the Service Endpoint:
  
  If the endpoint configuration is corrupted, try deleting and recreating the service endpoint in SOAMANAGER.
  Ensure all parameters are correctly set.
