Given a partner file and a Fusion object that do not line up, build the mapping and then PROVE IT with five payloads chosen to break it. Write the specification before opening the mapper. Target element, source, rule, and what happens when the source is absent — for EVERY target element including the ones you decide not to map. That table is the first deliverable, and building the mapping from it takes half as long as building it by exploration. THE SCHEMAS DO NOT LINE UP ON PURPOSE, and the mismatches are the exercise. One address line against several. A status vocabulary that does not correspond. A repeating structure at a different level. For each, decide whether it is a technical decision or a business question — and where it is a business question, write the question rather than inventing an answer. That is the graded part. Then the five…
