Changes vs D.96A
Top-level differences between D.96A and D.16B for the COPRAR message (segments directly inside header / detail / summary, ignoring nested groups). The comparison is indicative: a given tag may have evolved inside nested groups without showing up in this synthesis.

Structural example
Minimal example of an COPRAR D.16B message with mandatory segments only. The goal is to show the exact version declared in UNH (COPRAR:D:16B:UN) — not to replicate a full business case (see the COPRAR D.96A page for an annotated example).

UNZ+1+CTRL016001'Common errors
- Misaligned UNH tokens — The
UNH+...+COPRAR:D:16B:UNtoken must reflect exactly the directory in use — a mismatch between the UNH release and the release agreed with the partner is rejected by every strict validator. - Wrong UNT segment count — The value after
UNT+must include UNH and UNT themselves. By far the most common sender-side error, regardless of the directory in use. - Stale code lists — Between D.96A and D.16B, several code lists received new qualifiers (DTM status, RFF qualifier, NAD codes…). Reusing an older directory’s code tables triggers warnings or even rejections depending on the partner’s strict-conformance mode.
