  • What is the cause and solution for SAP error message S_CMI_CCV002 - RFC System failure; &1 &2 &3 &4 ?

    The SAP error message S_CMI_CCV002, which indicates an "RFC System failure," typically arises when there is an issue with the Remote Function Call (RFC) communication between SAP systems or between an SAP system and an external system. The parameters &1, &2, &3, and &4 in the error message usually provide additional context about the specific nature of the failure, such as the system name, the function module involved, or other relevant details.

    Causes:

    1. Network Issues: Problems with the network connection between the systems can lead to RFC failures.
    2. Configuration Errors: Incorrect settings in the RFC destination (SM59) can cause communication issues.
    3. Authorization Problems: The user credentials used for the RFC connection may not have the necessary authorizations.
    4. System Downtime: The target system may be down or not reachable.
    5. Resource Limitations: The system may be experiencing resource constraints (e.g., memory, CPU).
    6. Transport Layer Issues: Problems with the transport layer or middleware can also lead to RFC failures.

    Solutions:

    1. Check Network Connectivity: Ensure that the network connection between the systems is stable and functioning. You can use tools like ping or traceroute to diagnose connectivity issues.
    2. Review RFC Destination Configuration: Go to transaction code SM59 and check the configuration of the RFC destination. Ensure that the settings (such as the target host, system number, and client) are correct.
    3. Test RFC Connection: Use the "Connection Test" feature in SM59 to verify that the RFC destination is working correctly.
    4. Check User Authorizations: Ensure that the user credentials used for the RFC connection have the necessary authorizations to execute the required function modules.
    5. Monitor System Status: Check the status of the target system to ensure it is up and running. You can use transaction codes like SM51 to view the status of application servers.
    6. Review System Logs: Check the system logs (transaction SM21) for any related error messages that might provide more context about the failure.
    7. Check for Resource Issues: Monitor system performance and resource usage to identify any bottlenecks or limitations.
    8. Consult SAP Notes: Look for relevant SAP Notes that may address known issues related to RFC failures.

    Related Information:

    • Transaction Codes: SM59 (RFC Destinations), SM21 (System Log), SM51 (List of Active Servers), ST22 (Dump Analysis).
    • SAP Notes: Search the SAP Support Portal for notes related to RFC issues and the specific error message.
    • Documentation: Review SAP documentation on RFC and communication between systems for best practices and troubleshooting steps.

    If the issue persists after following these steps, it may be necessary to engage SAP support for further assistance.
