• What is the cause and solution for SAP error message CMM_DEND202 - A run (run ID &1) has already been started ?

  The SAP error message CMM_DEND202 indicates that a run with a specific run ID has already been started. This typically occurs in the context of processes that are designed to be executed only once at a time, such as batch jobs or data processing runs.
  Cause:
  
  Concurrent Execution: The most common cause of this error is that a previous instance of the run is still active or has not completed. This can happen if the job is taking longer than expected or if it has encountered an issue that prevents it from finishing.
  Manual Triggering: A user may have manually triggered the same run multiple times without waiting for the previous instance to complete.
  System Configuration: There may be system settings or configurations that restrict concurrent executions of certain processes.
  
  Solution:
  
  Check Active Runs: Use transaction codes like SM37 (Job Monitoring) to check if the run with the specified run ID is still active. If it is, you may need to wait for it to complete or investigate why it is taking longer than expected.
  Terminate Stuck Jobs: If you find that the previous run is stuck or has failed, you may need to terminate it. This can be done from the job monitoring screen by selecting the job and choosing the option to cancel or delete it.
  Review Logs: Check the logs associated with the run to identify any issues that may have caused it to hang or fail. This can provide insights into what went wrong and how to prevent it in the future.
  Adjust Scheduling: If this is a recurring issue, consider adjusting the scheduling of the runs to ensure that they do not overlap or conflict with each other.
  Consult Documentation: Review any relevant SAP documentation or notes related to the specific process you are running to ensure that you are following the correct procedures.
