  Rename the Alias: If you need to create a new alias, consider renaming it to something unique that does not conflict with existing aliases.

  Transport Management: If this issue arises during a transport, ensure that the target system does not already have the alias defined. You may need to adjust the transport request or manually resolve the conflict in the target system.
  Consult Documentation: Refer to SAP documentation or notes related to BOPF and alias management for additional guidance and best practices.
