Code lists are the smallest master data and the most copied. The guide shows how to govern them with the same versions, rules, security and audit as the big domains, and how to keep the crosswalk to every system's local codes.
| List | Why first |
|---|---|
| Countries and regions | used by every address, every tax rule, every restriction |
| Currencies and rates | every amount converts through them |
| Units of measure | every quantity depends on them; cycle consistency catches shipping errors |
| Payment terms and Incoterms | every order and every invoice |
Bring two systems that hold the same customers, suppliers or materials. In one working day we connect them, run the match on live rows, review the queue with your steward and publish the first golden view with its API.
