[System] Record added successfully.

12. Error Messages

Error CodeMessagePossible Cause
ERR001Invalid date format.Date not entered as YYYY‑MM‑DD.
ERR002Insufficient disk space.Less than 500 MB free on drive.
ERR003Record already exists.Duplicate primary key entered.

13. Error Handling

  • All input fields are validated before submission.
  • If an error occurs, the system highlights the offending field in red.
  • A tooltip explains the correction required.
  • Critical errors trigger a log entry in system.log and display a “Contact support” message.
