Yes, it’s possible to set up Odoo so that when you scan a barcode, it automatically fills into the search box. This can be achieved by using the onchange method in Odoo, which triggers an action when a specified field is altered. Here’s a simplified example:

class Product(models.Model):
    _name = 'product.product'

    barcode = fields.Char('Barcode')

    @api.onchange('barcode')
    def onchange_barcode(self):
        if self.barcode:
            # Your logic here to autofill fields

In this example, whenever the barcode field changes (i.e., when you scan a new barcode), the onchange_barcode method will be triggered. You can put your logic inside this method to autofill the fields you want.
