• What is the cause and solution for SAP error message CNVA_00555_MSG035 - RFC: &1 connection terminated/canceled ?

  The SAP error message CNVA_00555_MSG035 with the description "RFC: &1 connection terminated/canceled" typically indicates that a Remote Function Call (RFC) connection was unexpectedly terminated or canceled. This can happen for various reasons, and understanding the cause is essential for troubleshooting and resolving the issue.
  Possible Causes:
  
  Network Issues: Intermittent network connectivity problems can lead to RFC connections being dropped.
  Timeout Settings: If the RFC call takes too long to execute, it may exceed the timeout settings configured in the SAP system or the network.
  Resource Limitations: Insufficient resources on the application server (e.g., memory, CPU) can cause the server to terminate connections.
  Configuration Errors: Incorrect settings in the RFC destination or in the SAP Gateway configuration can lead to connection issues.
  System Load: High load on the SAP system can lead to performance issues, causing connections to be terminated.
  Firewall or Security Settings: Firewalls or security settings may block or terminate the connection unexpectedly.
  
  Solutions:
  
  Check Network Connectivity: Ensure that there are no network issues between the systems involved. Use tools like ping or traceroute to diagnose connectivity.
  Review Timeout Settings: Check the timeout settings for the RFC connection in the SAP system. You can adjust the timeout settings in transaction SM59 for the RFC destination.
  Monitor System Resources: Use transaction SM50 or SM66 to monitor the workload on the application server. If resources are low, consider optimizing performance or scaling resources.
  Validate RFC Configuration: Go to transaction SM59 and verify the configuration of the RFC destination. Ensure that all parameters are correctly set.
  Check System Logs: Review the system logs (transaction SM21) for any related error messages or warnings that could provide more context about the connection termination.
  Firewall Settings: If applicable, check firewall settings to ensure that they are not blocking or terminating the RFC connections.
  Update SAP Kernel: If the issue persists, consider updating the SAP kernel to the latest version, as there may be bug fixes related to RFC handling.
