Official status

Amazon documentation lists Unvalidated Settlement Flat File V2 migration 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.

What breaks

AreaBreakage
Code patternLegacy settlement report type or parser path for Unvalidated Settlement Flat File V2 migration.
Payload or schemaFlat File V2 is tab-delimited and collapses discrete fee/price columns into amount fields.
Permission or data accessFlat File V2 can require Finance and Accounting role access in Seller Central.
Pagination, status or field mappingHeader-name parsing, locale decimal commas and canonical totals replace positional parsing assumptions.

Before/after example

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

Before:
parseFlatFileV2(tsv); markCutoverReady();

After:
validateSettlementSample(tsv); reconcileCanonicalTotals(rows);
