• What is the cause and solution for SAP error message /IWFND/CM_BEC020 - RFC Error: SAP GW is not a trusted system or the security key is invalid ?

  The error message /IWFND/CM_BEC020 RFC Error: SAP GW is not a trusted system or the security key is invalid typically occurs in SAP Gateway scenarios when there is an issue with the trust relationship between the SAP Gateway system and the backend system. This can happen in various contexts, such as when trying to access OData services or when performing remote function calls (RFC).
  Causes:
  
  Trust Relationship Not Established: The SAP Gateway system is not recognized as a trusted system by the backend system.
  Invalid Security Key: The security key used for communication between the systems is incorrect or has not been set up properly.
  Configuration Issues: There may be misconfigurations in the RFC destination settings or in the SAP Gateway settings.
  Network Issues: Network connectivity problems between the systems can also lead to this error.
  Expired or Invalid Certificates: If you are using SSL, expired or invalid certificates can cause trust issues.
  
  Solutions:
  
  
  Establish Trust Relationship:
  
  Go to the backend system and check the trusted systems configuration.
  Use transaction code SM59 to configure the RFC destination. Ensure that the SAP Gateway system is added as a trusted system.
  In the backend system, navigate to Transaction SICF and check the service configuration for the OData service.
  
  
  
  Check Security Key:
  
  Ensure that the security key is correctly configured in both the SAP Gateway and the backend system.
  You can check the security settings in the backend system using transaction SPRO and navigating to the relevant security settings.
  
  
  
  Verify RFC Destination:
  
  In transaction SM59, check the settings of the RFC destination used by the SAP Gateway to connect to the backend.
  Ensure that the connection type is set correctly (e.g., T for TCP/IP connections) and that the target host and system number are correct.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no network issues preventing communication between the SAP Gateway and the backend system.
  You can use tools like ping or telnet to test connectivity.
  
  
  
  Review SSL Configuration:
  
  If SSL is being used, check the SSL configuration and ensure that the certificates are valid and not expired.
  You can use transaction STRUST to manage and check SSL certificates.
  
  
  
  Check Logs:
  
  Review the system logs (transaction SLG1) for any additional error messages that might provide more context about the issue.
