  Solution:
  To resolve the error, you should:
  
  
  Check the UID: Review the external UID you are trying to use and ensure it only contains valid characters. Remove any illegal characters such as spaces, special symbols (like @, #, $, etc.), or any other non-alphanumeric characters.
  
  
  Modify the UID: If the UID contains illegal characters, modify it to conform to the allowed character set. For example, if your UID is user@123, change it to user_123 or user123.
  
  
  Consult Documentation: Refer to the SAP documentation or your organization's guidelines for creating UIDs to ensure compliance with naming conventions.
  
  
  Test the Changes: After making the necessary changes, attempt to create or modify the user again to see if the error persists.
