  Remove or Modify Duplicate Entries: If you find that the pool already exists, you can either remove the duplicate entry or modify your configuration to use the existing pool instead of trying to create a new one.
  Review Configuration Documentation: Ensure that you are following the correct procedures for creating pools as per SAP documentation. This can help prevent configuration errors.
  Restart Services: In some cases, restarting the application server or relevant services may help clear any temporary issues that are causing the error.
