Supplier Catalog Comparison Tool — illustrative example

INPUT
Current SKU A costs 10; supplier update lists A at 12 and new SKU B at 8.

RESULT
A: price changed from 10 to 12. B: new record. Confirm currency and effective date before updating.

REVIEW
Catalog comparison needs an explicit matching key and change policy. Keep ambiguous matches separate from confirmed additions or removals.

This is a teaching example, not a live execution record.
