Hi!

Here's how you can solve your issue with displaying the last delivery date for a dropshipping partner in Odoo 15:

1. Use Odoo Studio Filters:

- Open the Studio tool and modify the partner form.

- Set the last_delivery field as a computed field.

- Write an expression that fetches the latest delivery date for the partner using the related stock.picking records. For example:

record.stock_picking_ids.filtered(lambda p: p.partner_id == record.id and p.dropship).sorted('date_done')[-1].date_done

2. Check Data Setup:

Ensure that your dropshipping records have the correct partner ID and delivery dates populated.

3. Test the Logic:

Save and test the field by navigating to a partner with dropshipping deliveries.
