What happens if I update the 'Original' column of a supplier CSV instead of the 'new' column?

If you are editing the CSV of a supplier that originates from a supplier feed, then the 'Original' columns are the data that is being pulled by that feed, and Xada will show you an error when attempting to import this CSV.

The only time that values are allowed to be entered into an 'Original' column is when a new supplier or supplier's products or new options are being created via CSV import.
