  Trim or Shorten Data: If the data exceeds the maximum length, consider trimming or shortening the value before assignment. This can be done programmatically or manually, depending on the context.
  Data Validation: Implement validation checks in your data entry or data processing logic to ensure that values conform to the expected lengths before attempting to save or process them.
  Adjust Field Length: If appropriate, consider adjusting the field length in the database or data structure to accommodate longer values. This should be done with caution and in accordance with your organization's data management policies.
