Account Payment Show Invoice

This module makes it easier to see, at a glance, which invoices a payment relates to. It does not create any new screen or menu; it simply enriches the existing Payments list in the Accounting application.

• In the Payments list view, a new column appears right after the partner (customer or vendor) column. It shows the related invoices as small tags, so you can immediately see which invoice(s) a payment is tied to without opening the payment.
• In the search panel of the same Payments list, the invoice field is added to the available filters. This means you can search or group payments by invoice, for example to find all payments linked to a specific invoice.

The module works on the account.payment model and only changes two existing views: the payment tree view and the payment search view. No new fields, no automatic computations, no validation rules, no emails or scheduled actions are added. The information displayed comes from the invoice links already recorded on the payment.

Because it only extends existing views, the change is visible anywhere the standard Payments list is used, including vendor payments and customer payments, as long as the standard payment views are in use.
