  Cause:
  The error can be caused by several factors, including:

  Permissions: Verify that the user has the necessary permissions to delete the mapping tables. You may need to adjust user roles or permissions accordingly.
  
  
  Database Locks: Check for any locks on the database that might be preventing the deletion. You can use database tools or SQL queries to identify and resolve locks.
  
  
  Manual Deletion: If the automated process fails, you may consider manually deleting the mapping tables using SQL commands, but this should be done with caution and ideally in a test environment first.
  
  
  Check Logs: Review the SLT or Data Services logs for more detailed error messages that can provide additional context on why the deletion failed.
