To set the products and categories not covered by discounts:
Go to Marketing → Exclusions in the management console.
Select products or categories from the drop-down list.
Click Add.
💡 Combine your dishes into categories to exclude them in bulk. As all of your dishes in a category are not covered with discounts and you don’t need to select Can’t be discounted to each dish manually.
☝️ Exclusions apply to customer groups and customer discounts only. Promotions still cover the excluded products. Don't mention a product in promotion in case you don't need that promotion to cover that specific product.
