## Official statement

> Coded charge reasons MUST belong to the UNCL 7161 code list

Source: https://docs.peppol.eu/poacc/billing/3.0/rules/ubl-tc434/BR-CL-20/

Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL

Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.

## Plain-language reading

A coded charge reason must belong to the UNCL 7161 code list. The statement says MUST, writes UNCL 7161 with a space, and has no period. The context is a charge whose charge indicator is true, with spaces around =. The test reads the element text and has a space after each comma. The list includes AA and ZZZ. The test does not call exists.

## What to change

On a charge, set the reason code to a value from the UNCL 7161 list, with no space in the code.

## Illustration

Illustration of the condition in the official statement. Not an example published by the source.

**Fails the stated condition.** A charge reason code contains a space, or it is not in the UNCL 7161 list.

**Passes the stated condition.** A charge reason code is AA, with no space.
