# ZUGFeRD 2.3.2 Mapping

## Overview

ZUGFeRD 2.3.2 is a maintenance release of the 2.3 standard, ensuring compatibility with the latest CII updates.

## Header Field Mapping

### Invoice Identification

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

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

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 `[1]`/`[2]`/`[3]`): 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.

| ZUGFeRD CII Path                                    | DocBits Field | Infor BOD Field | Type   | Description              |
| --------------------------------------------------- | ------------- | --------------- | ------ | ------------------------ |
| `ApplicableTradeTax/RateApplicablePercent` (tier 1) | `TAX_RATE`    | `TaxPercent`    | NUMBER | Standard-rate VAT (≥ 19) |
| `ApplicableTradeTax/BasisAmount` (tier 1)           | `NET_AMOUNT`  | `TaxableAmount` | AMOUNT | Standard-rate net amount |
| `ApplicableTradeTax/CalculatedAmount` (tier 1)      | `TAX_AMOUNT`  | `TaxAmount`     | AMOUNT | Standard-rate tax amount |

## Line Item Mapping

| ZUGFeRD CII Path                         | DocBits Field  | Infor BOD Field    | Type   | Description      |
| ---------------------------------------- | -------------- | ------------------ | ------ | ---------------- |
| `AssociatedDocumentLineDocument/LineID`  | `POSITION`     | `LineNumber`       | STRING | Line 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       |

# 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 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-2-3-2.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.
