  Cause:
  The error is caused by trying to create or use an identifier (like a transportation lane, route, etc.) that has already been defined in the system. This can happen due to:

  Use a Unique Identifier:
  
  When creating a new entry, ensure that the identifier you are using is unique. You may need to follow a naming convention or check for available identifiers.
