Product Transformation Rules using Item Class & Item EFFs

Summary: Product Transformation Rules using Item Class & Item EFFs

Content (required): We have a requirement to configure buy one get one promotion using Product Transformation Rules, we need to pull in information from Item Class and Attributes defined on the Item's EFF. Item class and Item EFFs attributes will derive the conditional logic for adding a product to the sales order line (as promotional item). We are not able to find any ADF Components in OrderTransformationRules that we can use in the If condition, we see ItemId and others but no components for Item EFF and Item Class. Please suggest how to achieve this.
