  Rename the Object: If the object name is invalid, rename it to comply with the naming conventions. For example, if the name starts with a number, change it to start with a letter.
  
  
  Review Code: If this error occurs in a program or function module, review the code to identify where the invalid name is being used and correct it.
  
  
  Consult Documentation: Refer to the SAP documentation or guidelines for naming conventions specific to the type of object you are working with (e.g., variables, classes, methods).
