  Rename or Delete Duplicates:

  Create New Functional Area:
  
  If you need to create a new functional area, ensure that the name you choose is unique and does not conflict with existing names.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to functional area configuration for additional guidance on best practices.
