Purchase Order Analytic Search

This module adds a way to find purchase orders through their analytic account, which is useful when you track costs by project, contract or cost centre.

• On the purchase order search bar a new "Analytic Account(s)" filter is available (only for users with analytic accounting rights). You can type the account code, its name or the project/account manager and Odoo returns the purchase orders whose lines use that analytic account.
• The same analytic account field is added to the purchase order line search, so you can filter order lines directly.
• A new menu entry under Purchasing lists purchase order lines; that list now shows the analytic account and the order status next to each line.

Behind the scenes, the analytic accounts of an order are gathered automatically from all its order lines, so the filter always reflects what is really recorded on the lines. The module only touches purchase orders and purchase order lines and their search/list screens; it does not change prices, taxes or approval rules.
