Structural example

Minimal example of an CONITT D.96A message with mandatory segments only. The goal is to show the exact version declared in UNH (CONITT:D:96A:UN) — not to replicate a full business case.

Common errors

• Misaligned UNH tokens — The UNH+...+CONITT:D:96A:UN token 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.96A, 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.
