  • What is the cause and solution for SAP error message SWF_HTTP308 - RFC error in the task generation ?

    The SAP error message SWF_HTTP308, which indicates an RFC (Remote Function Call) error during task generation, typically arises in the context of workflow processing. This error can occur for various reasons, and understanding the cause is essential for troubleshooting and resolving the issue.

    Possible Causes:

    1. Network Issues: There may be network connectivity problems between the SAP system and the RFC destination.
    2. RFC Destination Configuration: The RFC destination may not be correctly configured or may be pointing to an incorrect or inactive system.
    3. Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to execute the required function modules.
    4. System Load: High system load or performance issues can lead to timeouts or failures in RFC calls.
    5. Function Module Issues: The function module being called may not exist, may be inactive, or may have been changed in a way that affects its execution.
    6. Transport Layer Issues: If the error occurs during a transport, there may be issues with the transport layer or the transport request itself.

    Solutions:

    1. Check Network Connectivity: Ensure that there are no network issues between the systems involved. You can use tools like ping or traceroute to verify connectivity.
    2. Verify RFC Destination:
      • Go to transaction SM59 and check the configuration of the RFC destination.
      • Test the connection to ensure it is working correctly.
    3. Review Authorizations: Ensure that the user used for the RFC connection has the necessary authorizations to execute the required function modules.
    4. Monitor System Performance: Check system performance and load. If the system is under heavy load, consider optimizing performance or scheduling tasks during off-peak hours.
    5. Check Function Module: Verify that the function module being called exists and is active. You can do this by checking in transaction SE37 or SE80.
