Hi,

In Odoo SaaS 18.3+e, the barcode field is designed to automatically look up and fill in product details whenever a barcode is entered. This behavior is built-in to the Barcode module and cannot be disabled or patched directly in SaaS, since custom code changes are not allowed.

To work around this, you can use Odoo Studio to hide the default barcode field and instead create a custom field for manual barcode entry. That way, entering a barcode will not trigger the automatic product lookup. Another option is to simply leave the official barcode field empty and manually select products in forms or POS, adding your own barcode reference later if needed.

If you are using POS, you can also disable automatic scanning in the POS configuration to prevent products from being pulled up when scanning. However, the core auto-lookup behavior of the barcode field cannot be turned off in SaaS without these types of adjustments.

Hope it helps
