How should a Amazon returns report be built?应如何构建 Amazon 退货报告？
Use at least two return lenses. For FBA, the current FBA Returns Report (`GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA`) contains customer-returned items received at an Amazon fulfillment center and includes return date, order ID, SKU, ASIN, FNSKU, quantity, fulfillment center, detailed disposition, reason, status, license plate number and customer comments. Seller-fulfilled return-request reports have a different grain and scope. Join the correct shipped-item denominator, keep replacements, inventory ledger movements, refunds, fees and reimbursements separate, and calculate only a fully labeled mature-cohort rate.
至少使用两个退货视角。对于 FBA，当前 FBA 退货报告（`GET_FBA_FULFILLMENT_CUSTOMER_RETURNS_DATA`）包含 Amazon 运营中心已收到的客户退货，字段包括退货日期、订单 ID、SKU、ASIN、FNSKU、数量、运营中心、详细处置、原因、状态、容器号与客户评论。卖家自配送退货申请报告具有不同粒度与范围。关联正确的发货商品行分母，分开换货、库存台账移动、退款、费用与赔偿，只计算标签完整的成熟群组比例。
Amazon report types and fields change. This page reflects official Selling Partner API documentation reviewed September 15, 2026. Amazon currently documents the FBA Returns Report as received customer returns with daily updates, while seller-fulfilled return reports cover return requests; confirm current report roles and availability before extraction. The U.S. is the target market, but marketplace and program availability must remain explicit. The Customer Feedback API provides return insights only at browse-node level, refreshes weekly and is English-only; it is not an ASIN-level physical-return ledger.
Amazon 报告类型与字段会变化。本文反映 2026 年 9 月 15 日核验的 Selling Partner API 官方文档。Amazon 当前把 FBA 退货报告定义为已收到的客户退货并每日更新，而卖家自配送退货报告覆盖退货申请；提取前应确认当前角色与可用性。目标市场为美国，但必须明确站点与项目可用性。客户反馈 API 的退货洞察仅到浏览节点，每周刷新且只提供英文；它不是 ASIN 级实体退货台账。
Keep seven Amazon evidence layers separate分开七个 Amazon 证据层
A customer case can appear in several Amazon sources at different times and grains. Preserve each source-native record first, then build canonical events through documented identifiers and relationships. A matching SKU, amount or date is not sufficient proof of identity.
一个客户案例可能以不同时间和粒度出现在多个 Amazon 来源中。先保留每条平台原生记录，再通过文档化标识与关系构建规范事件。相同 SKU、金额或日期不足以证明记录相同。
Marketplace, seller account, fulfillment channel, order and item IDs, SKU, catalog identifier, quantity, sale-time label, price, currency and purchase time.站点、卖家账户、履约渠道、订单与商品行 ID、SKU、目录标识、数量、销售时标签、价格、币种与购买时间。
Shipped quantity, shipment/item ID, ship date, fulfillment location and service establish the eligible denominator and return-opportunity clock.发货数量、发货/商品行 ID、发货日期、履约地点与服务用于建立合格分母和退货机会时钟。
Request or authorization identifiers, request date, requested quantity, reason, comment, status and seller- or platform-fulfilled scope.申请或授权标识、申请日期、申请数量、原因、评论、状态，以及卖家或平台履约范围。
Receipt date, received quantity, facility, condition or disposition, inspection evidence and license-plate or tracking identifiers where documented.文档支持时的收货日期、实收数量、设施、状态或处置、质检证据以及容器或追踪标识。
Replacement order, original order, quantity, inventory ledger movement, restockability, removal, adjustment and downstream inventory state.换货订单、原订单、数量、库存台账移动、可重新销售性、移除、调整与下游库存状态。
Refund event, settlement or transaction reference, amount, tax, shipping, fees, reimbursements, currency and posting status—kept separate from physical receipt.退款事件、结算或交易引用、金额、税、运输、费用、赔偿、币种与入账状态，并与实体收货分离。
Carrier invoices and scans, third-party warehouse receipt/inspection, support contacts, labor, refurbishment, disposal, liquidation, supplier recovery and contribution data.承运商发票与扫描、第三方仓库收货/质检、客服联系、人工、翻新、销毁、清算、供应商回收与贡献数据。
The FBA Returns Report describes items received at an Amazon fulfillment center. It should not be used as a complete seller-fulfilled return-request file, refund ledger or all-marketplace denominator. Conversely, an MFN request is not proof of carrier acceptance or seller receipt.
FBA 退货报告描述 Amazon 运营中心已收到的商品，不能当作完整卖家自配送退货申请文件、退款台账或所有站点分母。反过来，MFN 申请也不能证明承运商已接收或卖家已收货。
Map Amazon records to explicit analytical events把 Amazon 记录映射为明确分析事件
Keep source-native report names and fields in the raw layer. Add canonical event, quantity, timestamp and state only in a governed semantic layer. Record the report/API version, requested window, extraction time, marketplace, role and fulfillment scope with every load.
原始层保留平台原生报告名与字段。仅在受治理语义层增加规范事件、数量、时间与状态。每次加载都记录报告/API 版本、请求窗口、提取时间、站点、角色与履约范围。

Worked example: Amazon return totals disagree示例：Amazon 退货总数不一致
A synthetic U.S. seller has 20,000 eligible shipped item units in mature, fulfillment-specific cohorts. The FBA Returns Report contains 1,260 units received at fulfillment centers. Seller-fulfilled files contain 340 authorized requests, of which carrier or warehouse evidence confirms 255 receipts. Finance records show 1,430 refunded units across both scopes, and the replacement report contains 180 issued replacement units. These counts legitimately differ.
一个模拟美国卖家的履约范围成熟群组有 20,000 件合格发货商品。FBA 退货报告包含运营中心实收 1,260 件。卖家自配送文件有 340 件已授权申请，其中承运或仓库证据确认实收 255 件。财务记录在两个范围内显示 1,430 件退款，换货报告包含 180 件已发换货。这些数量合理地不同。
| Synthetic view模拟视图 | Units件数 | Rate vs shipped相对发货比例 | Correct use正确用途 |
|---|---|---|---|
| FBA received returnsFBA 实收退货 | 1,260 | 6.3% | FBA physical receipt lensFBA 实体收货视角 |
| Verified MFN receipts已核验 MFN 实收 | 255 | 1.275% | MFN physical receipt lensMFN 实体收货视角 |
| Refunded units退款件数 | 1,430 | 7.15% | Financial outcome under chosen rule所选规则下财务结果 |
| Issued replacement units已发换货件数 | 180 | 0.9% | Replacement workflow lens换货工作流视角 |
Do not add or overwrite these rates without checking denominators and overlap. The all-scope physical receipt numerator is 1,515 only if the FBA and verified MFN records are mutually exclusive, the 20,000 denominator covers the same scopes, and each item had equal observation time. Refunded and replacement units remain separate outcomes.
在检查分母与重叠前，不要相加或覆盖这些比例。只有当 FBA 与已核验 MFN 记录互斥、20,000 件分母覆盖相同范围，且每件商品观察机会相同时，全部范围实体实收分子才是 1,515。退款与换货件仍是独立结果。
All store figures and records in this example are synthetic. They illustrate the method and do not represent InfiniSynapse customer results or industry benchmarks.本示例中的商店数字与记录均为模拟，仅用于说明方法，不代表 InfiniSynapse 客户结果或行业基准。
Treat Amazon as multiple governed sources, not one ledger把 Amazon 视为多个受治理来源，而不是单一台账
A Amazon report is scoped evidence. It does not automatically contain every return request, carrier movement, physical receipt, condition, refund, fee, reimbursement or recovery outcome. Use source-specific completeness tests and reconcile expected overlaps before producing a cross-channel metric.
一份 Amazon 报告是有范围的证据，不会自动包含每次退货申请、承运移动、实体收货、状态、退款、费用、赔偿或回收结果。生成跨渠道指标前，应针对来源测试完整性并核对预期重叠。
Orders, item identifiers, marketplace, fulfillment scope, sale-time catalog context and platform-native status.订单、商品行标识、站点、履约范围、销售时目录背景与平台原生状态。
Shipment, carrier, receipt, facility, condition/disposition, inventory ledger and removal evidence.发货、承运、收货、设施、状态/处置、库存台账与移除证据。
Refund, settlement, fee, reimbursement, tax, currency and posting date—never inferred from a reason code.退款、结算、费用、赔偿、税、币种与入账日期，绝不能从原因码推断。
Seller warehouse, carrier invoice, support, inspection, labor, supplier and recovery sources with measured coverage.带有实测覆盖的卖家仓库、承运商发票、客服、质检、人工、供应商与回收来源。
Amazon states that near-real-time and daily FBA reports have generation limits, and individual reports document their own freshness. Store requested ranges, report IDs, generated timestamps and rerun history so a later file does not silently overwrite an earlier observation.
Amazon 说明准实时与每日 FBA 报告存在生成频率限制，各报告还会记录自身时效。应保存请求范围、报告 ID、生成时间与重跑历史，防止后续文件静默覆盖早期观察。
Run twelve controls before trusting a Amazon returns report信任 Amazon 退货报告前完成十二项控制
- Source contract: report/API, version, role, permission, marketplace, fulfillment scope and generation time are recorded.来源契约：记录报告/API、版本、角色、权限、站点、履约范围与生成时间。
- Event contract: request, authorization, shipment, receipt, inspection, disposition, replacement, refund and reimbursement remain distinct.事件契约：申请、授权、发货、收货、质检、处置、换货、退款与赔偿保持分离。
- Stable identity: order/item, shipment/item, return, refund, replacement, SKU and catalog identifiers survive label changes.稳定身份：订单/商品行、发货/商品行、退货、退款、换货、SKU 与目录标识不受标签变更影响。
- Quantity reconciliation: ordered, shipped, requested, authorized, received, replaced, refunded and restocked units are compared.数量核对：比较下单、发货、申请、授权、实收、换货、退款与重新入库件数。
- Fulfillment scope: platform-fulfilled and seller-fulfilled sources are separated and coverage is reported.履约范围：分开平台履约与卖家履约来源，并报告覆盖。
- Mature cohort: eligible shipped units have equal observation opportunity under one window and as-of date.成熟群组：合格发货件在统一窗口与截至日期下具有相同观察机会。
- Reason quality: reason version, customer comment, other, unknown, changed and missing values are quantified.原因质量：量化原因版本、客户评论、其他、未知、已更改与缺失值。
- Condition separation: customer reason, received condition, disposition and inventory outcome use different fields.状态分离：客户原因、收货状态、处置与库存结果使用不同字段。
- Financial reconciliation: refunds, fees, taxes, reimbursements, currencies and posting dates are explicit.财务核对：明确退款、费用、税、赔偿、币种与入账日期。
- Freshness: documented cadence, generation limits, late arrivals, reruns and restatements are monitored.时效：监控文档化频率、生成限制、迟到记录、重跑与重述。
- External coverage: carrier, WMS, inspection, labor, disposal and recovery gaps remain visible.外部覆盖：承运商、WMS、质检、人工、销毁与回收缺口保持可见。
- Security: minimum roles, sensitive-field minimization, retention, deletion, export access and audit logs are enforced.安全：执行最小角色、敏感字段最小化、保留、删除、导出访问与审计日志。
Avoid nine Amazon return-report mistakes避免九个 Amazon 退货报告错误
- Treating a customer-selected reason as a verified root cause.把客户选择的原因当作已核验根因。
- Combining customer reason, observed condition, disposition, and refund outcome in one field.把客户原因、观察状态、处置与退款结果混在一个字段。
- Changing code labels without versioning or remapping historical records.更改代码标签却不进行版本化或映射历史记录。
- Ranking percentages without counts, eligible denominators, value, or uncertainty.只按百分比排序，不展示数量、合格分母、金额或不确定性。
- Comparing products, channels, or periods with different question wording and missingness.比较问题措辞与缺失程度不同的商品、渠道或期间。
- Discarding “other,” free text, multi-reason, changed, or unknown responses.丢弃“其他”、自由文本、多原因、已更改或未知回答。
- Acting on correlation before reviewing cases and testing a mechanism.在检查案例并测试机制前就依据相关性行动。
- Using the FBA received-returns report as a complete all-channel return-request report.把 FBA 实收退货报告当作完整全渠道退货申请报告。
- Treating browse-node return topics from Customer Feedback as ASIN-level physical return counts.把客户反馈中的浏览节点退货主题当作 ASIN 级实体退货数量。
When Amazon sources disagree, preserve every source value, compare documented scope and timing, reconcile by stable IDs, and keep unresolved records visible. Choosing the preferred total creates false precision and prevents later audit.
当 Amazon 来源不一致时，保留每个来源值，比较文档化范围与时间，用稳定 ID 核对，并让未解析记录保持可见。选择偏好的总数会制造虚假精确并妨碍后续审计。
Start with one Amazon marketplace and one decision从一个 Amazon 站点与一个决策开始
Choose one seller account, marketplace, fulfillment scope, mature cohort and decision such as SKU prioritization. Extract the minimum documented reports, reconcile request, receipt, refund and replacement events, publish coverage and late-arrival behavior, join the minimum external operational evidence, and validate the metric with operations and finance before scaling.
选择一个卖家账户、站点、履约范围、成熟群组与决策，例如 SKU 优先级。提取最少必要官方报告，核对申请、收货、退款与换货事件，发布覆盖与迟到行为，关联最少必要外部运营证据，并在扩展前与运营和财务验证指标。
| Signal信号 | Evidence to check待检查证据 | Safe next step安全下一步 |
|---|---|---|
| Need product return prioritization需要商品退货优先级 | Stable item IDs, mature shipped cohort, physical receipt and reason/condition coverage稳定商品行 ID、成熟发货群组、实体收货与原因/状态覆盖 | Build one reconciled marketplace view建立一个已核对站点视图 |
| Need refund and fee control需要退款与费用控制 | Refund, settlement, fee, tax, reimbursement, currency and posting records退款、结算、费用、税、赔偿、币种与入账记录 | Keep cash events separate from receipt保持资金事件与收货分离 |
| Need root-cause action需要根因行动 | Reason, comments, condition, inspection, catalog, support and fulfillment evidence原因、评论、状态、质检、目录、客服与履约证据 | Form and test a mechanism形成并测试机制 |

Current official documentation says it contains customer-returned items received at an Amazon fulfillment center, including return date, order ID, SKU, ASIN, FNSKU, quantity, fulfillment center, detailed disposition, reason, status, license-plate number and customer comments. It is updated daily.当前官方文档说明它包含 Amazon 运营中心已收到的客户退货，包括退货日期、订单 ID、SKU、ASIN、FNSKU、数量、运营中心、详细处置、原因、状态、容器号与客户评论，并每日更新。
No. A return report can represent a request or physical receipt depending on the report type. Refunds, fees, reimbursements and settlement postings are financial events and require separate reconciliation.不等于。退货报告可按报告类型代表申请或实体收货。退款、费用、赔偿与结算入账属于财务事件，需要单独核对。
Normalize both to canonical events, keep the fulfillment scope, reconcile stable order/item IDs and use an aligned shipped-item cohort. Do not combine FBA receipts with MFN requests as one numerator.把两者规范为统一事件，保留履约范围，用稳定订单/商品行 ID 核对，并使用对齐的发货商品行群组。不要把 FBA 实收与 MFN 申请放进同一分子。
The current official API documentation says return insights are available only at browse-node level, while review insights can be available at ASIN and browse-node level. Do not infer an ASIN physical return rate from browse-node topics.当前官方 API 文档说明退货洞察仅在浏览节点级提供，而评论洞察可在 ASIN 与浏览节点级提供。不要从浏览节点主题推断 ASIN 实体退货率。
Use item-level shipment records with marketplace, fulfillment channel, order and item identifiers, SKU/FNSKU/ASIN, shipped quantity and shipment date. Apply exclusions and a mature observation window consistently.使用包含站点、履约渠道、订单与商品行标识、SKU/FNSKU/ASIN、发货数量与日期的商品行级发货记录，并一致应用排除规则与成熟观察窗口。
