• What is the cause and solution for SAP error message /SDF/E2E758 - No timezone check could be performed due to RFC failures ?

  The SAP error message /SDF/E2E758 No timezone check could be performed due to RFC failures typically indicates that there is an issue with Remote Function Call (RFC) connections in your SAP system. This error can occur in various scenarios, particularly when the system is trying to perform timezone checks that require communication with another system or service via RFC.
  Causes:
  
  RFC Connection Issues: The most common cause is that the RFC connection to the target system is not functioning properly. This could be due to network issues, incorrect configuration, or the target system being down.
  Authorization Problems: The user credentials used for the RFC connection may not have the necessary authorizations to perform the required operations.
  Configuration Errors: Incorrect settings in the RFC destination configuration (e.g., incorrect host, port, or system ID) can lead to failures.
  System Availability: The target system may be unavailable or experiencing issues that prevent it from responding to the RFC calls.
  Firewall or Network Issues: Firewalls or network configurations may be blocking the communication between the systems.
  
  Solutions:
  
  
  Check RFC Connections:
  
  Go to transaction SM59 in the SAP GUI and check the status of the RFC destination that is being used for the timezone check.
  Test the connection to ensure it is working properly. If it fails, investigate the error message provided.
  
  
  
  Review Configuration:
  
  Ensure that the RFC destination is correctly configured with the right parameters (e.g., hostname, service, client, user, password).
  Verify that the target system is reachable from the source system.
  
  
  
  Check Authorizations:
  
  Ensure that the user credentials used for the RFC connection have the necessary authorizations to perform the required operations.
  
  
  
  Network and Firewall Settings:
  
  Check for any network issues or firewall settings that may be blocking the RFC communication.
  Ensure that the necessary ports are open and that there are no network outages.
  
  
  
  System Availability:
  
  Verify that the target system is up and running. If it is down, coordinate with the system administrators to resolve the issue.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and the developer trace (transaction ST22) for any additional error messages that may provide more context about the RFC failures.
