  Review Input Data: If the error occurs during data entry, review the input data for any non-numeric characters. Ensure that users are aware of the expected input format.
  Debugging: If you are working with custom ABAP code, use debugging tools to trace the execution and identify where the non-numeric value is being assigned to the numeric field.
  Error Handling: Implement error handling in your code to catch such issues and provide meaningful feedback to users.
