Account Invoice View Payment

This module makes it easier to move between an invoice and its payment in Odoo Accounting.

On a customer invoice or vendor bill, a "View Payments" link appears under the payments widget. It is only shown when the invoice already has payments, and only for users with invoicing rights. Clicking it opens the related payment: if there is only one payment, its form opens directly; if there are several, a list of those payments is shown. For vendor bills and vendor refunds the list is filtered to payable payments, otherwise the standard payments list is used.

On the payment form, a "Validate & View Payment" button is added next to the normal validate button. Pressing it validates the payment and then immediately opens the payment record itself, which is handy when a follow-up step is needed, for example printing a check.

The module extends the account.move and account.payment models and modifies the invoice form and payment form views. It does not add new menus, reports or scheduled actions.
