• What is the cause and solution for SAP error message CNV_OM_PRESEL060 - Replication is still running - Incremental Preselection not possible ?

  The SAP error message CNV_OM_PRESEL060 indicates that an incremental preselection cannot be performed because a replication process is still running. This error typically occurs in the context of data migration or data replication scenarios, particularly when using SAP's Landscape Transformation (SLT) or other data replication tools.
  Cause:
  
  Ongoing Replication: The primary cause of this error is that there is an active replication process that is currently running. This means that the system is still processing data changes, and as a result, it cannot perform an incremental preselection until the ongoing replication is completed.
  Locking Mechanism: The replication process may have a locking mechanism that prevents other operations from being executed simultaneously to ensure data consistency.
  
  Solution:
  
  
  Check Replication Status: 
  
  Use transaction codes like SLG1 (Application Log) or LTMOM (LT Master Data Migration) to check the status of the replication process. Look for any active jobs or processes that might be running.
  
  
  
  Wait for Completion: 
  
  If you find that a replication job is running, you may need to wait for it to complete. Monitor the job status and ensure that it finishes successfully.
  
  
  
  Terminate Long-Running Jobs: 
  
  If a replication job is taking too long and you suspect it may be stuck, you can consider terminating it. However, be cautious with this approach as it may lead to data inconsistencies. Use transaction SM37 to monitor and manage background jobs.
  
  
  
  Retry Incremental Preselection: 
  
  Once you confirm that no replication processes are running, you can retry the incremental preselection operation.
  
  
  
  System Performance: 
  
  If replication jobs frequently take a long time, consider reviewing system performance and tuning the replication settings to optimize the process.
  
  
  
  Related Information:
  
  Documentation: Refer to SAP Help documentation for Landscape Transformation (SLT) or the specific data migration tool you are using for more details on replication processes and error handling.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Community Forums: Engage with SAP community forums or support channels for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the CNV_OM_PRESEL060 error and successfully perform the incremental preselection.
