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

The Document level charge amount (BT-99) may have at most 2 decimals. The statement says "allowed maximum number of decimals" and "is 2", and it ends with a period. It does not say shall. The context writes ChargeIndicator = true() with spaces around =. The published test is the same string as BR-DEC-01. It reads cbc:Amount and writes <=2 with no space before <=. It does not call exists.

## What to change

Send the Document level charge amount (BT-99) with at most 2 digits after the decimal point.

## Illustration

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

**Fails the stated condition.** The document-level charge amount has 3 digits after the decimal point.

**Passes the stated condition.** The document-level charge amount has 2 digits after the decimal point.

## Published context and test

```
