Settlement posted-date-time vs settlement-end-date

Settlement posted-date-time vs settlement-end-date focuses on migration mapping and reconciliation evidence, not generic API copy. Use it to turn a vague migration into a reviewable test case.

Official status

Amazon documentation lists legacy settlement period date assumptions as in-scope for this migration. Use the official source before code freeze because deadlines and replacement details can change.

Production Settlement validation plan

Settlement migration is a finance parser rebuild. The production gate is not simply requesting the new report type; it is proving that amount rows, currencies, descriptions and totals reconcile under realistic sample files.

Validation areaProduction proof to collect
Report typeConfirm no code path still requests XML or the legacy flat-file report type.
Parser contractParse by header name and retain amount-type, amount-description, amount and currency together.
Locale handlingValidate decimal comma and decimal point samples with deterministic decimal arithmetic.
Accounting totalsReconcile principal, fees, refunds and transfers before replacing close workflows.

Mapping table

Settlement posted-date-time vs settlement-end-date should be implemented as a small, reviewable mapping table before release.

Validation scenario

Validate one settlement containing late refunds or adjustments posted near the period boundary.

Parser or reconciliation example

Use this as the shape of the unit test or review snippet; adjust names to your codebase.

const periodKey = settlementEndDate;
const rowTime = parsePostedDateTime(row['posted-date-time']);
assert(rowTime <= settlementEndDate.plus(gracePeriod));

What breaks

AreaBreakage
Code patternCode still assumes legacy settlement period date assumptions.
Payload or schemaThe migration target is Flat File V2 row posted-date-time plus settlement period metadata, so shape, naming or grouping changes.
Permission or data accessField visibility, role access or accounting availability can differ by marketplace and workflow.
Pagination, status or field mappingMapping mistakes can hide under successful HTTP responses unless samples are reconciled.

Before/after example

The example is intentionally small so the migration shape is visible in a code review.

Before:
// Old assumption
legacy settlement period date assumptions

After:
const periodKey = settlementEndDate;
const rowTime = parsePostedDateTime(row['posted-date-time']);
assert(rowTime <= settlementEndDate.plus(gracePeriod));

FAQ

What should Settlement posted-date-time vs settlement-end-date prove?

It should prove that legacy settlement period date assumptions maps safely to Flat File V2 row posted-date-time plus settlement period metadata for the tested workflow.

What evidence belongs in the ticket?

The source finding, mapping table result, sample input, normalized output and reconciliation note.

Can the page replace production validation?

No. It gives the mapping contract and sample gate; production rollout still needs staged validation.

How does the scanner help?

It flags AMZ-SET-DATE-001, AMZ-SET-RECON-001 evidence and links findings to the relevant mapping or validator page.
