# ZUGFeRD 2.0 Mapping

## Overview

ZUGFeRD 2.0 was designed to be compliant with the European standard EN 16931. It uses the UN/CEFACT CII D16B structure.

## Header Field Mapping

### Invoice Identification

| ZUGFeRD CII Path                  | DocBits Field       | Infor BOD Field    | Type   | Description        |
| --------------------------------- | ------------------- | ------------------ | ------ | ------------------ |
| `ExchangedDocument/ID`            | `INVOICE_NUMBER`    | `DocumentID`       | STRING | Invoice number     |
| `ExchangedDocument/TypeCode`      | `INVOICE_TYPE_CODE` | `DocumentType`     | STRING | Invoice type code  |
| `ExchangedDocument/IssueDateTime` | `INVOICE_DATE`      | `DocumentDateTime` | DATE   | Invoice issue date |

### Document Type & Sub-Type (TRA-driven)

Alongside the raw `INVOICE_TYPE_CODE`, the default TRANSFORMATION XSLT emits two derived fields:

| DocBits Field      | Source                                                                                                     | Logic                                                                    |
| ------------------ | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
| `INVOICE_TYPE`     | `CrossIndustryInvoice/ExchangedDocument/TypeCode`                                                          | UNCL 1001 `381` or `261` → **Credit Note**; any other code → **Invoice** |
| `INVOICE_SUB_TYPE` | `SupplyChainTradeTransaction/ApplicableHeaderTradeAgreement/BuyerOrderReferencedDocument/IssuerAssignedID` | Non-empty → **Purchase Invoice**; empty/missing → **Cost Invoice**       |

### Tax Breakdown (Tier-classified)

`ApplicableTradeTax` blocks are distributed across three rate-based tiers (not positional indexes): standard-rate fields (`TAX_RATE` / `NET_AMOUNT` / `TAX_AMOUNT`) capture rate ≥ 19; reduced-rate fields (`*_2`) capture 0 < rate < 19; zero-rate fields (`*_3`) capture rate = 0. See [ZUGFeRD Tax Breakdown](/administration-and-setup/settings/global-settings/document-types/edi/zugferd.md#tax-breakdown-tier-classified) for the full field list.

### Dates

| ZUGFeRD CII Path                                    | DocBits Field   | Infor BOD Field      | Type | Description        |
| --------------------------------------------------- | --------------- | -------------------- | ---- | ------------------ |
| `ActualDeliverySupplyChainEvent/OccurrenceDateTime` | `DELIVERY_DATE` | `ActualShipDateTime` | DATE | Delivery/ship date |
| `SpecifiedTradePaymentTerms/DueDateDateTime`        | `DUE_DATE`      | `PaymentDueDateTime` | DATE | Payment due date   |

### Supplier (Seller) Information

| ZUGFeRD CII Path                                   | DocBits Field        | Infor BOD Field       | Type   | Description    |
| -------------------------------------------------- | -------------------- | --------------------- | ------ | -------------- |
| `SellerTradeParty/ID`                              | `VENDOR_ID`          | `SupplierPartyID`     | STRING | Supplier ID    |
| `SellerTradeParty/Name`                            | `VENDOR_NAME`        | `SupplierPartyName`   | STRING | Supplier name  |
| `SellerTradeParty/PostalTradeAddress/Line1`        | `VENDOR_ADDRESS`     | `SupplierAddress1`    | STRING | Address line 1 |
| `SellerTradeParty/PostalTradeAddress/PostcodeCode` | `VENDOR_POSTAL_CODE` | `SupplierPostalCode`  | STRING | Postal code    |
| `SellerTradeParty/PostalTradeAddress/CityName`     | `VENDOR_CITY`        | `SupplierCity`        | STRING | City           |
| `SellerTradeParty/PostalTradeAddress/CountryID`    | `VENDOR_COUNTRY`     | `SupplierCountryCode` | STRING | Country code   |

## Line Item Mapping

| ZUGFeRD CII Path                         | DocBits Field  | Infor BOD Field    | Type   | Description         |
| ---------------------------------------- | -------------- | ------------------ | ------ | ------------------- |
| `AssociatedDocumentLineDocument/LineID`  | `POSITION`     | `LineNumber`       | STRING | Line number         |
| `SpecifiedTradeProduct/BuyerAssignedID`  | `ITEM_NUMBER`  | `BuyerItemID`      | STRING | Buyer's item number |
| `SpecifiedTradeProduct/Name`             | `DESCRIPTION`  | `ItemDescription`  | STRING | Item description    |
| `BilledQuantity`                         | `QUANTITY`     | `InvoicedQuantity` | NUMBER | Billed quantity     |
| `NetPriceProductTradePrice/ChargeAmount` | `UNIT_PRICE`   | `UnitPrice`        | AMOUNT | Net unit price      |
| `LineTotalAmount`                        | `TOTAL_AMOUNT` | `ExtendedAmount`   | AMOUNT | Line total          |

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.docbits.com/administration-and-setup/settings/global-settings/document-types/edi/zugferd/zugferd-2-0.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
