This post was published in August 2014 and introduces a module built for Odoo V7. It does not work with current versions.
We have released a list view for invoice lines.
A little surprisingly, Odoo has no standard list view at line level, so we built a community module for it. With this, every invoice line can be seen on one screen. We have added Japanese translations for the field labels as well.
Here is where you can download it — do give it a try!
It looks like a simple customisation — “take the invoice lines and add referenced fields from the invoice document level” — but getting the exchange rate, and grouping records by a document-level field, both take a little contrivance. Have a look at the source if that interests you.
