In Odoo 17, how can I manage product variants in POS, such as coffee sizes and order types (dine-in vs. takeaway with extra cup), without creating separate products for each variant? I need accurate inventory tracking based on selected attributes and want to set up a Bill of Materials (BoM) that adjusts based on attributes like size and consumption type.

 I’ve set the “Variants Creation Mode” to “Never (option)” to avoid separate products, but now the attributes aren’t appearing in the BoM.
