  Review Dependencies: If the domain is already in use, you may need to review any dependencies or references to that domain before renaming it. Ensure that renaming does not break any existing functionality.
  
  
  Create New Domain: If renaming is not feasible due to dependencies, consider creating a new domain with a unique name and linking it appropriately.
  
  
  Consult Documentation: If you are unsure about the implications of renaming or creating new domains, consult SAP documentation or seek advice from a knowledgeable SAP consultant.
  
  
  Related Information:
