  Check Custom Code:
  
  If custom code is involved, review the code to ensure that it does not create duplicate area names.
  Make necessary adjustments to ensure uniqueness.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport logs and the objects being transported to identify any duplicates.
  Correct the configurations in the source system and re-transport if necessary.
