GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request	November 11, 2026	Use the supported retrieval/report document path and validate role plus availability	A blind retry loop can delay finance close and hide the unsupported request shape until the legacy report deadline is near.

Official status

Amazon documentation lists GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request 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 area	Production proof to collect
Report type	Confirm no code path still requests XML or the legacy flat-file report type.
Parser contract	Parse by header name and retain amount-type, amount-description, amount and currency together.
Locale handling	Validate decimal comma and decimal point samples with deterministic decimal arithmetic.
Accounting totals	Reconcile principal, fees, refunds and transfers before replacing close workflows.

Quick answer

GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 not allowed at this time usually means Amazon rejected the report request at that time, often because the request path, availability window or report-generation assumption is wrong. The fastest check is: Preserve the raw error and inspect the request method, reportType, marketplace and role scope.

Why this happens

This troubleshooting page is tied to GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request, not a generic SP-API failure.

Cause	What to verify
Cause 1	The code uses POST createReport for a settlement report type that is not allowed in that context.
Cause 2	The seller, marketplace or settlement period does not have an available generated report yet.
Cause 3	Role or account access is incomplete, so the report exists but the app cannot access it.
Cause 4	Retry code hides the exact InvalidInput message and loses the reportType evidence.

How to detect it in your code

Search the source, scheduled jobs, generated clients, report configuration and sample fixtures before assuming the issue is only live data.

POST /reports/2021-06-30/reports
{ "reportType": "GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2" }
// 400 InvalidInput: not allowed at this time

Fix checklist

Log the redacted request method, endpoint, reportType and marketplace.
Check whether the workflow should list/retrieve existing settlement reports instead of creating one.
Verify Finance and Accounting role access for the seller account.
Check settlement period availability before retrying.
Route successful report documents through the Flat File V2 parser validator.
Re-scan source for legacy settlement constants and createReport misuse.

Migration risk

A blind retry loop can delay finance close and hide the unsupported request shape until the legacy report deadline is near.

Production surface	Risk if ignored
Accounting/order/support workflow	A blind retry loop can delay finance close and hide the unsupported request shape until the legacy report deadline is near.
Release gate	The migration can look complete while the runtime job still fails or silently loses data.
Audit evidence	Without a preserved sample, reviewers cannot distinguish an accepted limitation from a migration bug.

How API Migration Guard checks it

API Migration Guard scans for exact operation names, report type constants, endpoint strings, query parameters, parser assumptions and token/window loops. Paid reports add file-level findings, remediation notes, sample validation steps, CSV/JSON/SARIF exports and an evidence package.

Rule	Evidence	Validation
AMZ-SET-CREATE-001, AMZ-SET-REPORT-001	GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request	Re-scan source for legacy settlement constants and createReport misuse.

Removed resource and replacement

Old resource	Replacement	Deadline	Validation outcome
GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request	Use the supported retrieval/report document path and validate role plus availability	November 11, 2026	A blind retry loop can delay finance close and hide the unsupported request shape until the legacy report deadline is near.

What breaks

Area	Breakage
Code pattern	Runtime or source evidence points at GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request.
Payload or schema	Amazon rejected the report request at that time, often because the request path, availability window or report-generation assumption is wrong.
Permission or data access	The code uses POST createReport for a settlement report type that is not allowed in that context.
Pagination, status or field mapping	Retry code hides the exact InvalidInput message and loses the reportType evidence.

Before/after example

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

Before:
POST /reports/2021-06-30/reports
{ "reportType": "GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2" }
// 400 InvalidInput: not allowed at this time

After:
// Fix path: Use the supported retrieval/report document path and validate role plus availability
// Validate with API Migration Guard, sample evidence and a re-scan.

Scanner detection

Rule ID	Severity	Evidence pattern	False positive condition	Validation step
AMZ-SET-CREATE-001, AMZ-SET-REPORT-001	HIGH for runtime error evidence; BLOCKER when tied to removed resources	GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 request	Documentation, comments, generated clients or test fixtures can require manual review.	Log the redacted request method, endpoint, reportType and marketplace.

Migration checklist

FAQ

How do I fix GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 not allowed at this time?

Confirm the request evidence, apply the Use the supported retrieval/report document path and validate role plus availability path, validate the sample and re-scan.

Can API Migration Guard detect GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 not allowed at this time?

It detects source patterns related to AMZ-SET-CREATE-001, AMZ-SET-REPORT-001 and shows evidence, remediation notes and validation steps.

Does the free scan call Amazon?

No. It scans uploaded or pasted source statically and can validate pasted samples without Amazon credentials.

When should this become a paid report?

When the free scan finds matching production evidence and the team needs file-level findings, SARIF, CSV or handoff artifacts.
