  Solution:
  To resolve this error, you should:
  
  
  Check the Characteristic Group Name: Ensure that the name you are trying to assign to the characteristic group contains at least one letter. For example, instead of using a name like "12345" or "!!!", use a name like "GroupA1" or "Characteristics_01".
  
  
  Modify the Name: If the name you are using is purely numeric or contains special characters, modify it to include alphabetic characters. 
  
  
  Follow Naming Conventions: Make sure that the name adheres to any specific naming conventions or guidelines set by your organization or the SAP system.
  
  
  Re-attempt the Action: After modifying the name, try to create or modify the characteristic group again.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or the specific documentation for the module you are working with for more details on naming conventions and requirements.
  Transaction Codes: If you are working within a specific transaction (like CT04 for characteristics), ensure you are familiar with the fields and requirements of that transaction.
