Building a field map for Hong Kong payment reporting packs
A field map ties each reported figure to a query, owner, and last successful reconciliation date.
Reporting packs fall apart when figures are assembled from tribal knowledge. A field map lists every number in the supervisory or board pack, the system of record, the exact extract or query, the owner, and the date of the last independent reconciliation.
During a reporting accuracy audit we pressure-test that map: re-run extracts for a locked period, compare to the filed pack, and note any manual overrides. Manual steps are allowed when controlled; undocumented overrides are not.
Keep the map versioned alongside fee schedules and product catalogues. When a new wallet product launches, the map should change in the same release train as the product.
