Account Invoice Refund Reason

This module adds a small reference list of refund reasons that you maintain yourself, and makes that list available when you create a credit note.

Where it appears in Odoo: - Under Accounting configuration there is a new "Refund Reasons" menu where you can create, edit and archive reasons. Each reason has a name (translated), an optional description and an active flag. - On the credit note wizard (the screen used to reverse an invoice or bill) a new "Refund Reason" field is shown and is mandatory; the old free-text reason field is hidden. - On the resulting credit note itself, the chosen reason is displayed in the invoice form, read-only, next to the reference.

Business behaviour: - When you confirm the reversal, the reason you selected is automatically copied onto every credit note created from that reversal, so you do not have to type it again. - The reason name is also copied into the wizard's text reason field automatically. - A set of common reasons (cancellation, price difference, data correction, etc.) is loaded when the module is installed. - Accounting users can read the reason list; only accounting managers can create, change or delete reasons.

It touches the invoice/bill model account.move, the reversal wizard account.move.reversal and adds the new model account.move.refund.reason.
