Answer 1

product_id = fields.Many2one('product.product', string='Product', required=True, default=lambda self: self._default_product_id())

 @api.model
    def _default_product_id(self):
        latest_line = self.env['mk.voucher.line'].search([], order="id desc", limit=1)
        return latest_line.product_id.id if latest_line else False
