  • What is the cause and solution for SAP error message WFRE_CON211 - Communication failure occured ?

    The SAP error message WFRE_CON211: Communication failure occurred typically arises in the context of SAP Workflow when there is a problem with the communication between the workflow runtime environment and the workflow container or other workflow components.


    Cause

    • Communication failure between workflow runtime and workflow container: This error usually indicates that the workflow runtime environment (WF Runtime Engine) could not communicate properly with the workflow container or the workflow engine.
    • Network or RFC connection issues: The underlying cause might be related to Remote Function Call (RFC) communication problems, such as network interruptions, incorrect RFC destinations, or authorization issues.
    • Incorrect or missing configuration: Workflow runtime environment or workflow container might not be properly configured.
    • System load or performance issues: High system load or resource constraints can cause timeouts or communication failures.
    • Transport or patch inconsistencies: Sometimes, missing patches or inconsistent transport requests can cause workflow communication errors.

    Solution

    1. Check RFC Connections:

      • Verify the RFC destinations used by the workflow runtime environment.
      • Use transaction SM59 to test the RFC connections.
      • Ensure that the RFC destinations are correctly configured and active.
    2. Check Workflow Runtime Environment:

      • Use transaction SWU3 (Automatic Workflow Customizing) to check and activate workflow settings.
      • Ensure that the workflow runtime environment is properly configured and active.
    3. Check Workflow Logs:

      • Use transaction SWI1 or SWI2_FREQ to analyze workflow logs and identify where the communication failure occurs.
      • Look for any related error messages or dumps in ST22.
    4. Check System Performance and Network:

      • Verify that the system is not overloaded.
      • Check network connectivity between the involved systems if the workflow spans multiple systems.
    5. Check Authorization:

      • Ensure that the user or service account running the workflow has the necessary authorizations.
    6. Apply SAP Notes:

      • Search for relevant SAP Notes related to WFRE_CON211 on the SAP Support Portal.
      • Apply any recommended patches or corrections.
    7. Restart Workflow Runtime:

      • Sometimes restarting the workflow runtime environment or the SAP system can resolve transient communication issues.
