Acccount Move Accounting Sale Order Description

This module changes what appears on customer invoices created from sale orders. It works together with the module that adds an accounting description field on products.

When an invoice is generated from a sale order, each invoice line normally copies the sales description of the product. With this module, if the product has an accounting description filled in, that text is used as the invoice line description instead.

The original sales description is not lost: it is stored as the external note of the invoice line, so it can still be seen on the invoice.

• Applies automatically when invoicing sale orders; no new menu or button is added.
• Only affects lines that have a product linked to them.
• If the product has no accounting description, the behaviour stays as before.
• The module is installed automatically when its dependencies are present.

It touches the sale order line model (sale.order.line) and the way invoice lines are prepared, and relies on the product accounting description field. No new reports, emails, scheduled jobs or restrictions are added by this code.
