• What is the cause and solution for SAP error message SOI191 - Live clone: Sync trigger is created in later task than log trigger ?

  The SAP error message SOI191, which states "Live clone: Sync trigger is created in later task than log trigger," typically occurs in the context of SAP HANA database operations, particularly when dealing with live cloning or replication scenarios. This error indicates that there is a misconfiguration in the sequence of triggers that manage the synchronization of data between the source and target systems.
  Cause:
  The error arises when the synchronization trigger (which is responsible for managing the data replication) is created after the log trigger (which captures the changes in the source database). This sequence is critical because the synchronization process needs to be aware of the changes captured by the log trigger to ensure data consistency and integrity during the cloning or replication process.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Trigger Sequence: Review the sequence in which the triggers are created. Ensure that the synchronization trigger is created before the log trigger. This may involve modifying the order of operations in your cloning or replication script.
  
  
  Recreate Triggers: If the triggers have already been created in the wrong order, you may need to drop the existing triggers and recreate them in the correct order. Make sure to follow the proper sequence:
  
  Create the log trigger first.
  Then create the sync trigger.
  
  
  
  Review Configuration: Ensure that your configuration settings for the live clone or replication process are correct. This includes checking any parameters or settings that dictate the order of operations.
  
  
  Consult Documentation: Refer to the official SAP HANA documentation for live cloning and replication to ensure that you are following the recommended practices and guidelines.
  
  
  Testing: After making the necessary changes, test the cloning or replication process in a development or test environment before applying it to production.
  
  
  Related Information:
  
  SAP HANA Documentation: Always refer to the latest SAP HANA documentation for detailed information on triggers, replication, and live cloning.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Support: If the issue persists after following the above steps, consider reaching out to SAP Support for further assistance.
  
  By ensuring the correct order of trigger creation and following best practices, you should be able to resolve the SOI191 error and successfully perform live cloning or replication in SAP HANA.
