Fusion item master and Product Hub mapped to D365 product data
How Fusion's item master, item classes, category hierarchies, extensible flexfields, and organisation assignment pattern map to D365's product master, released products, product dimension groups, storage and tracking dimensions, and category hierarchies.
What you will be able to do
Map Fusion item-master constructs to D365 product master and released product
Choose the correct D365 product dimension group for each Fusion tracking policy
Translate Fusion item classes and category hierarchies to D365 procurement and product categories
Explain why Fusion's organisation assignment is the closest analogue to D365's release-to-legal-entity pattern
Introduction
Fusion's product data model is centred on the item master — a single master record shared across all Inventory Organisations, extended through Item Classes, Extensible Flexfields, and catalogue structures.
Fusion item master and Product Hub
Items are the master records. Each item has attributes covering description, units of measure, lead times, sourcing rules, and costing flags. Items exist at the master level and are assigned to specific Inventory Organisations, where per-organisation overrides (localised descriptions, organisation-specific UOM, sourcing rules) can be…
The item master mapped to D365
Assigning a Fusion item to an Inventory Organisation makes it available for transactions within that org — receiving, issuing, manufacturing, and inventory management. The closest D365 analogue is releasing a product to a legal entity: creating a released product record that makes the product transactable within that company.
Product dimension groups and tracking
D365 uses three types of dimension groups to control how a product is tracked and stored.
Category hierarchies, UOM, and product lifecycle
Category hierarchies in D365 serve multiple purposes: the Procurement category hierarchy replaces Fusion's purchasing categories and procurement catalog structure; the Retail hierarchy (if Commerce is in scope) handles retail assortments; and the Commodity code hierarchy handles statistical and trade-compliance classification.

Summary
Fusion's item master translates to D365's product master plus released product model with good fidelity. The biggest design decisions are the dimension group assignments and the attribute migration strategy for EFFs.
