This error indicates that there is an issue with the change table name, which is crucial for tracking changes in the source system for replication to the target system.
  Cause:
  The error can be caused by several factors, including:
  
  Change Table Name Conflict: The change table name might already exist in the target system, or there may be a naming conflict due to existing tables.
  Incorrect Configuration: The configuration settings for the SLT replication might not be set up correctly, leading to issues in identifying or creating the change tables.

  Adjust Naming Conventions: If there are naming conflicts, consider adjusting the naming conventions used for change tables in the SLT configuration.
  
  
  Database Permissions: Ensure that the user account used for the SLT replication has the necessary permissions to create tables in the target database.
  
  
  Check for Transport Issues: If the configuration was transported, review the transport logs for any errors or warnings that might indicate issues with the change table naming.
