Hello, I have not been able to get this code to work, could you tell me exactly what I should replace in the code?

Hi,

In Odoo, the Many2one field defaults to displaying records in ascending order. and if you need to change the default order and limit the number of records displayed you can try this code :

partner_id = fields.Many2one( 'res.partner', string='Partner',
        compute='_compute_partner_id', store=True)

    def _compute_partner_id(self):        for record in self:
            ordered_partners = self.env['res.partner'].sudo().search([], order='id desc', limit=5)
            if ordered_partners:
                for partner in ordered_partners:
                    record.partner_id = partner.id

This code ensures that the partner_id field is computed based on the first five partners in descending order according to their IDs. Replace the field name and model according to your specific requirements.

Hope it helps
