INVRPT — EDIFACT Inventory Report Message (D.16B)

The INVRPT message is the periodic inventory report sent by a stock holder (warehouse, point of sale, logistics platform) to a manufacturer or central buyer: it carries stock levels per item and per location, inbound and outbound movements, recalls of available quantity and stockouts. It is central to VMI (Vendor Managed Inventory) and co-managed inventory schemes. This page summarises the segment structure as published by UN/CEFACT for directory D.16B.

Purpose

Changes vs D.96A

Top-level differences between D.96A and D.16B for the INVRPT 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.

Segments added vs D.96A

• FTX in the header section (status C, repeat ×99) — not present at the top of the corresponding D.96A section.
• FTX in the detail section (status C, repeat ×99) — not present at the top of the corresponding D.96A section.
• CTA in the detail section (status M, repeat ×1) — not present at the top of the corresponding D.96A section.
• COM in the detail section (status C, repeat ×9) — not present at the top of the corresponding D.96A section.
• GIR in the detail section (status M, repeat ×1) — not present at the top of the corresponding D.96A section.

Status changes (M ↔ C)

• NAD (detail): status M in D.96A → C in D.16B.
• INV (detail): status C in D.96A → M in D.16B.

Structural example

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

Common errors

• Misaligned UNH tokens — The UNH+...+INVRPT:D:16B: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.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.
