Purchase Order Product Attachment Mgmt

This module makes it easy to find every document linked to the products you are buying, without opening each product one by one.

On the purchase order form, next to the existing buttons, a new "Attachments" button appears. Clicking it opens a window listing all attachments that belong to the products on the order lines, including attachments stored on the related product templates.

• The list is built automatically from the products used in the order lines.
• It covers both product.product and product.template attachments.
• In that window, creating and editing attachments is disabled, so it works as a read-only overview.

The same action is also available from the purchase order list view through the standard "Action" menu, because the module registers a server action bound to the purchase.order model.

No new fields, no automatic checks, no emails or scheduled jobs are added. The module only extends purchase.order with the logic needed to collect and display these attachments, and it depends on the standard Purchase app.
