  • What is the cause and solution for SAP error message SMM002 - Resource error occurred at RFC destination & ?

    The SAP error message SMM002, which states "Resource error occurred at RFC destination &," typically indicates that there is an issue with the Remote Function Call (RFC) destination that is being used to connect to another SAP system or external system. This error can arise due to various reasons, including configuration issues, network problems, or resource limitations.

    Causes:

    1. RFC Destination Configuration: The RFC destination may not be configured correctly. This includes incorrect connection parameters, such as the target system's IP address, system number, client, user credentials, etc.

    2. Network Issues: There may be network connectivity problems between the SAP system and the target system. This could be due to firewalls, routing issues, or network outages.

    3. Resource Limitations: The target system may be experiencing resource limitations, such as high CPU usage, memory issues, or too many concurrent connections.

    4. Authorization Issues: The user credentials used in the RFC destination may not have the necessary authorizations to perform the requested operation.

    5. System Configuration: The target system may not be properly configured to accept RFC calls, or it may be down for maintenance.

    Solutions:

    1. Check RFC Destination Configuration:

      • Go to transaction SM59 in the SAP GUI.
      • Locate the RFC destination that is causing the error.
      • Verify the connection parameters (e.g., target host, system number, client, user, password).
      • Test the connection using the "Connection Test" button to see if it succeeds.
    2. Network Troubleshooting:

      • Ensure that there are no network issues preventing communication between the systems.
      • Check firewall settings to ensure that the necessary ports are open for RFC communication.
    3. Monitor System Resources:

      • Check the target system for resource usage (CPU, memory, etc.) to ensure it is not overloaded.
      • If the target system is down or undergoing maintenance, wait until it is back online.
    4. Review User Authorizations:

      • Ensure that the user credentials used in the RFC destination have the necessary authorizations to perform the required actions.
    5. Check System Logs:

      • Review the system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
    6. Consult SAP Notes:
