# ZUGFeRD 2.1 映射

## 概述

ZUGFeRD 2.1 与法国标准 Factur-X 1.0 完全相同。它完全符合 EN 16931，广泛用于德国与法国之间的跨境交易。

## 页眉字段映射

### 发票标识

| ZUGFeRD CII 路径                    | DocBits 字段          | Infor BOD 字段       | 类型     | 描述     |
| --------------------------------- | ------------------- | ------------------ | ------ | ------ |
| `ExchangedDocument/ID`            | `INVOICE_NUMBER`    | `DocumentID`       | STRING | 发票编号   |
| `ExchangedDocument/TypeCode`      | `INVOICE_TYPE_CODE` | `DocumentType`     | STRING | 发票类型代码 |
| `ExchangedDocument/IssueDateTime` | `INVOICE_DATE`      | `DocumentDateTime` | DATE   | 发票开具日期 |

### 文档类型和子类型（由 TRA 驱动）

除原始 `INVOICE_TYPE_CODE` 外，默认 TRANSFORMATION XSLT 还会生成两个派生字段：

| DocBits 字段         | 来源                                                                                                         | 逻辑                                                |
| ------------------ | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------- |
| `INVOICE_TYPE`     | `CrossIndustryInvoice/ExchangedDocument/TypeCode`                                                          | UNCL 1001 `381` 或 `261` → **贷项通知单**；其他代码 → **发票** |
| `INVOICE_SUB_TYPE` | `SupplyChainTradeTransaction/ApplicableHeaderTradeAgreement/BuyerOrderReferencedDocument/IssuerAssignedID` | 非空 → **采购发票**；空或缺失 → **费用发票**                     |

### 税额明细（按层级分类）

`ApplicableTradeTax` 区块会按税率分配到三个层级（而非按位置索引）：标准税率字段（`TAX_RATE` / `NET_AMOUNT` / `TAX_AMOUNT`）用于捕获税率 ≥ 19 的数据；低税率字段（`*_2`）用于捕获 0 < 税率 < 19 的数据；零税率字段（`*_3`）用于捕获税率 = 0 的数据。完整字段列表请参阅[ZUGFeRD 税额明细](/chinese/guan-li-yu-she-zhi/settings/global-settings/document-types/edi/zugferd.md#tax-breakdown-tier-classified)。

### 买方信息

| ZUGFeRD CII 路径                                    | DocBits 字段            | Infor BOD 字段          | 类型     | 描述    |
| ------------------------------------------------- | --------------------- | --------------------- | ------ | ----- |
| `BuyerTradeParty/ID`                              | `COMPANY_ID`          | `CustomerPartyID`     | STRING | 客户 ID |
| `BuyerTradeParty/Name`                            | `COMPANY_NAME`        | `CustomerPartyName`   | STRING | 公司名称  |
| `BuyerTradeParty/PostalTradeAddress/Line1`        | `COMPANY_ADDRESS`     | `CustomerAddress1`    | STRING | 地址行 1 |
| `BuyerTradeParty/PostalTradeAddress/PostcodeCode` | `COMPANY_POSTAL_CODE` | `CustomerPostalCode`  | STRING | 邮政编码  |
| `BuyerTradeParty/PostalTradeAddress/CityName`     | `COMPANY_CITY`        | `CustomerCity`        | STRING | 城市    |
| `BuyerTradeParty/PostalTradeAddress/CountryID`    | `COMPANY_COUNTRY`     | `CustomerCountryCode` | STRING | 国家代码  |

## 行项目映射

| ZUGFeRD CII 路径                           | DocBits 字段             | Infor BOD 字段       | 类型     | 描述     |
| ---------------------------------------- | ---------------------- | ------------------ | ------ | ------ |

| `BilledQuantity/@unitCode`               | `UNIT`                 | `UnitCode`         | STRING | 计量单位   |
| `NetPriceProductTradePrice/ChargeAmount` | `UNIT_PRICE`           | `UnitPrice`        | AMOUNT | 不含税单价  |
| `LineTotalAmount`                        | `TOTAL_AMOUNT`         | `ExtendedAmount`   | AMOUNT | 行项目总额  |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.docbits.com/chinese/guan-li-yu-she-zhi/settings/global-settings/document-types/edi/zugferd/zugferd-2-1.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
