Custom Metadata Engine — A custom metadata engine lets you attach arbitrary pass-through fields — cost centers, PO numbers, project codes — to accounts, subscriptions, and line items. Those fields ride through quoting and billing untouched, landing on invoices and in the data warehouse where finance needs them.
Custom Metadata Engine (Pass-Through Fields) lives in the Design & Setup phase of Define What You Sell — the stage where you design the catalog, pricing, and rules of the offer. In the corpus tool index this phase maps to the CPQ and Billingcategories.
