  • What is the cause and solution for SAP error message UR479 - Run &1 is active - the undo function cannot be used ?

    The SAP error message UR479 indicates that a specific run (identified by &1) is currently active, and therefore, the undo function cannot be executed. This error typically occurs in the context of batch processing or job scheduling within SAP, where a particular job or run is still in progress, preventing any undo operations.

    Cause:

    1. Active Job: The primary cause of this error is that the job or run you are trying to undo is still active. This means that the system is currently processing the data associated with that run.
    2. Concurrency Issues: If multiple users or processes are trying to access or modify the same data simultaneously, it can lead to this error.
    3. System Locking: SAP uses locking mechanisms to ensure data integrity. If a run is locked for processing, you cannot perform an undo operation until it is completed.

    Solution:

    1. Wait for Completion: The simplest solution is to wait until the active run completes. Once the job is finished, you should be able to perform the undo operation without any issues.
    2. Check Job Status: Use transaction codes like SM37 (Job Monitoring) to check the status of the job. If it is still running, you may need to wait or investigate why it is taking longer than expected.
    3. Terminate the Job: If the job is stuck or taking too long, you may consider terminating it. However, this should be done with caution, as it can lead to data inconsistencies. You can terminate a job from the SM37 transaction by selecting the job and choosing the "Cancel" option.
    4. Consult with Basis Team: If you are unsure about terminating a job or if the job is critical, consult with your SAP Basis team or system administrator for guidance.
    5. Review Logs: Check the application logs or job logs for any errors or warnings that might indicate why the job is taking longer than expected.

    Related Information:

    • Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 for job monitoring, SM21 for system logs, and SLG1 for application logs.
    • SAP Notes: Check SAP Notes for any known issues or patches related to the specific version of SAP you are using.
    • Documentation: Review SAP documentation for best practices on job scheduling and management to avoid similar issues in the future.

    By following these steps, you should be able to resolve the UR479 error and successfully perform the desired operations in SAP.
