• What is the cause and solution for SAP error message CM_SCC_OD_INTEGRATIO020 - Synchronization already running; execution canceled ?

  The SAP error message CM_SCC_OD_INTEGRATIO020 indicates that a synchronization process is already running, and as a result, the system has canceled the new execution request. This error typically occurs in the context of SAP Landscape Management (LaMa) or when using the SAP Cloud Connector for integration scenarios.
  Cause:
  
  Concurrent Execution: The most common cause of this error is that a synchronization job is already in progress. SAP does not allow multiple instances of the same synchronization process to run simultaneously to prevent data inconsistencies or conflicts.
  Stuck Processes: Sometimes, a previous synchronization process may not have completed properly and is still marked as running in the system.
  Configuration Issues: Misconfigurations in the synchronization settings or scheduling can lead to overlapping execution times.
  
  Solution:
  
  
  Check Running Jobs: 
  
  Go to the relevant transaction (e.g., SM37 for job monitoring) to check if there is an active synchronization job. If you find one, you may need to wait for it to complete or terminate it if it is stuck.
  
  
  
  Terminate Stuck Processes: 
  
  If you identify a stuck process, you can terminate it using transaction SM37 or through the appropriate management interface. Ensure that you understand the implications of terminating a job, as it may lead to data inconsistencies.
  
  
  
  Review Scheduling: 
  
  If the synchronization jobs are scheduled, review the scheduling settings to ensure that they do not overlap. Adjust the timing to prevent concurrent executions.
  
  
  
  Logs and Traces: 
  
  Check the logs for any additional error messages or warnings that might provide more context about why the synchronization is stuck or why it was not able to complete.
  
  
  
  System Restart: 
  
  In some cases, a system restart may help clear any lingering processes that are not visible in the job monitoring tools.
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation related to the specific synchronization process you are using for any additional troubleshooting steps or best practices.
