At present the Market Messages Database (ver 4.1) contains the contents of Message 506 (DUoS

structure will be removed from the Messages database (and will not appear in the Message
Implementation Guide for DUoS). The structure will be presented to Suppliers in Business Scenarios for
DUoS billing document.
