  Numbers (0-9)
  Underscores (_)
  
  
  
  Rename the Structure: If the name contains any special characters, rename the evaluation structure to comply with SAP's naming conventions. For example, instead of using a name like Eval-Structure#1, you could use Eval_Structure1.
  
  
  Avoid Reserved Words: Ensure that the name does not conflict with any reserved words or existing objects in the SAP system.
  
  
  Test the Changes: After renaming, try to save or activate the evaluation structure again to see if the error persists.
