What a contract-level feature is
A feature is a commercial modifier, something that changes how a phase behaves, rather than a product you’re selling. You configure features from the Configure Features panel on a phase, and they apply across everything in that phase rather than to one product alone. This is a different, smaller set of features from the ones you can attach to an individual product’s pricing. Use a contract-level feature when you want something to apply across the whole phase, and a product-level feature when it should only affect one specific product.The six contract-level feature types
Free units and grants aren’t contract-level features. If you need to grant a pool of usage or a block of free units, configure that on the product itself instead. See features: concepts for the product-level feature set.
