Account Mass Reconcile by Sale Line

This module extends the mass reconciliation tool in Odoo's Accounting app. When you create a mass reconciliation rule, you can now choose the method 'Advanced. Product, sale order line.' from the list of available reconciliation methods.

• The rule matches debit and credit journal items that share the same sale order line. It also requires that both the product and the sale order line are filled in on the line; lines missing either value are skipped.
• It supports matching multiple debit entries against multiple credit entries and allows partial reconciliation.
• The reconciliation form shows a new section called 'Advanced. Sale Order Line' with a short explanation of how the matching works.
• The method is available to all internal users.

This is designed for companies using perpetual inventory accounting, where goods delivered but not yet invoiced are posted to an accrual account. The module touches the account.mass.reconcile model, the account.mass.reconcile.method model, and the advanced reconciliation engine. It relies on the sale order line information being present on journal items, which is provided by the account_move_line_sale_info module.
