• What is the cause and solution for SAP error message DAAG_COMMON123 - Tables cannot be deleted while upgrade is running ?

  The SAP error message DAAG_COMMON123 indicates that there is an attempt to delete database tables while an upgrade process is still running. This is a common issue that can occur during system upgrades or migrations when certain operations are not allowed to be performed concurrently.
  Cause:
  The primary cause of this error is that the upgrade process is actively modifying the database schema, which includes creating, modifying, or deleting tables. During this time, the system locks certain tables to ensure data integrity and consistency. Attempting to delete tables while these locks are in place will trigger the error message.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Upgrade Status: Verify if the upgrade process is still running. You can do this by checking the logs or the upgrade status in the SAP system.
  
  
  Wait for Completion: If the upgrade is still in progress, you will need to wait until it completes. Once the upgrade is finished, you should be able to perform the table deletion without encountering this error.
  
  
  Review Logs: If you believe the upgrade has completed but you are still encountering this error, review the upgrade logs for any issues or errors that may have occurred during the process.
  
  
  Restart the Upgrade: If the upgrade process seems to be stuck or has failed, you may need to restart the upgrade process. Ensure that you follow the proper procedures for restarting an upgrade.
  
  
  Check for Locks: Use transaction codes like SM12 to check for any locks that may be preventing the deletion of tables. If there are locks that are no longer needed, you can release them.
  
  
  Consult Documentation: Refer to the SAP upgrade documentation for any specific instructions or considerations related to your version and upgrade path.
  
  
  Contact SAP Support: If the issue persists and you are unable to resolve it, consider reaching out to SAP support for assistance.

  Upgrade Documentation: Always refer to the official SAP upgrade guides and notes for your specific version, as they may contain important information regarding known issues and best practices.
  System Backup: Ensure that you have a backup of your system before performing any upgrades or major changes to avoid data loss.
