  Remove or replace the invalid character with a valid one (e.g., use underscores _ or other allowed characters).
  
  
  Data Validation: Implement data validation checks to ensure that only valid characters are entered in the future. This can be done through user exits or validation rules.
  Reprocess Data: After correcting the data, reprocess the relevant planning runs or data loads to ensure that the changes take effect.
