  Check for Other Errors:
  
  After updating the configuration, check for any other related error messages that may indicate further issues with the replication process.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for SLT for detailed steps on how to handle schema changes and update the configuration.
