Account Mass Reconcile by Purchase Line

This module extends the mass reconciliation tool in Odoo's accounting. When you create a mass reconciliation rule on an account, you can now choose an extra method called 'Advanced. Product, purchase order line.'

• The rule appears on the same mass reconciliation form, under the Information tab, in a section labelled 'Advanced. Purchase Order Line'.
• The method matches multiple debit entries against multiple credit entries and allows partial reconciliation.
• To be matched, journal items must share the same partner, the same product and the same purchase order line.
• Journal items that have no product or no purchase order line are skipped and left out of the reconciliation.
• The available matching columns now include the product and the purchase order line from the journal item.

It touches the mass reconciliation models (account.mass.reconcile, account.mass.reconcile.method) and the advanced reconciliation engine (mass.reconcile.advanced), and adds a new reconciliation method model. It is intended for companies using perpetual inventory accounting, where the accrual account 'Goods Received Not Invoiced' needs to be cleared by matching stock receipts with supplier invoices per purchase order line.
