IFTMCS — EDIFACT Instruction Contract Status Message (D.96A)

The IFTMCS message is the formal status of a transport contract (firm booking, counter-proposal, refusal) returned by a carrier or forwarder to the principal after an IFTMIN or IFTMBF instruction: it references the originating instruction, sets the accepted or counter-proposed terms, and materialises the transport contractual commitment. This page summarises the segment structure as published by UN/CEFACT for directory D.96A.

Changes vs D.96A

This page documents directory D.96A itself: it serves as the reference for every other version of the message. The synthesis below describes the structural changes that later directories will introduce relative to it.

No top-level differences detected between D.96A and D.96A for this message. Differences are then limited to nested groups and code lists.

Structural example

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

Common errors

• Misaligned UNH tokens — The UNH+...+IFTMCS: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.
