- MSAnsweredHello,
May I know the reason for duplication? Please ask separate question but if you have already asked that in reply there is no need to ask again. Now I am not sure where to follow :(
Here is my reply from your other question

Reference number is not validated against uniqueness as it's manual input. You can add new validation rule for reference `is_unique[sales.reference_no]` and the full line would be
```php
$this->form_validation->set_rules('reference_no', $this->lang->line('reference_no'), 'required|is_unique[sales.reference_no]');
```
in the sales controller `app/controllers/Sales.php`
