How to Exclude unpurchasable products?

An unpurchasable product has its price as empty value or ‘woocommerce_is_purchasable’ set to false. It is done to keep the products in the catalog but hold its sale temporarily. As these products are not meant for selling, you might wish to exclude them from attribute listing as linked variations.

If so, follow these steps:

• Go to the Linked Variations Settings tab on the plugin dashboard.
• In the Basic Configuration section, select yes for the Exclude Unpurchasable products option.
• Click on the Save Changes button.
