EN 16931
FATAL
The document-level allowance amount (BT-92) is written with more than 2 decimals. Monetary amounts in EN 16931 are capped at 2 decimal places.
How to fix it
- Serialize the amount with at most 2 decimals:
25.50, not25.5000. - Fix the formatter, not the stored value - internal precision may stay higher.
Official rule text
The allowed maximum number of decimals for the Document level allowance amount (BT-92) is 2.
