  The SAP error message GU301 indicates that you are trying to create an object (such as a variable, field name, or other identifiers) that begins with a numeral. In SAP ABAP, object names cannot start with a number; they must begin with a letter (A-Z, a-z) or an underscore (_).

  Check Naming Conventions: Ensure that the new name adheres to SAP's naming conventions, which typically allow:
  
  Names to start with letters (A-Z, a-z) or underscores (_).
  Names to contain letters, numbers (0-9), and underscores.
  Names to be of a certain length (usually up to 30 characters).
