Test purchases, returns, earning events, and redemptions around the statement date and program year end. Issuers may post rewards after the underlying purchase or reverse them after a return appears on a later statement. Keep the issuer's event sequence intact. A cutoff difference belongs in the bridge; it should not be removed by assigning an invented transaction date.
When terms change, close the old program version with its own unit roll-forward and begin the new version with the documented conversion. Reperform the conversion for a sample of accounts. If the issuer supplies only a combined opening balance, record that limitation rather than allocating units to historical purchases without evidence.
Compare expired units with notices and administrator access logs where available. The purpose is to determine whether the expiration was recorded and reviewed, not to claim that every expiration was avoidable. If management reinstates units, record the reinstatement as a new event and retain the issuer confirmation.
Review annual fees and reward credits independently. A card can have a net economic presentation in management reporting, but the reconciliation should preserve the fee payment and reward event separately. This also prevents a fee refund or retention offer from being mislabeled as an ordinary reward redemption.
For noncash redemptions, verify receipt or use without assigning an unsupported market value. A canceled booking may return points, cash, both, or neither. Trace each component into the later unit and cash bridges, and keep open exceptions for delayed refunds.
Carry control totals through downloads and transformations. Portal opening units plus activity should agree with closing units before enrichment. The imported event count should agree with the source count after documented rejects. Monetary redemption totals should agree with the statement-credit population, and that population should agree with the ledger bridge. Missing rows, unsupported formats, and truncated histories remain listed exceptions.
Complete a subsequent-activity review for open redemptions and expected reinstatements. Later activity belongs in a dated event rather than the frozen period, but it may resolve an uncertainty. Confirm that a later credit has not already been booked manually and through the card feed.
