+In odoo, user has the possibility to rename the "description" field of an invoice line, and at the same time delete / alter the product code.
+But in some situation, removing the product code is a problem, because it should be present on the invoice report.
+
+This module avoids this problem.
+
+For that purpose, this module adds a new dedicated column "Default code"
+in the account invoice report.
+As a side effect, it improves readability of the invoices.
