EDIFACT INVRPT – Inventory Report (D.96A)

EDIFACT INVRPT (Inventory Report) is a globally recognized UN/EDIFACT message standard used to communicate inventory balances, availability, and stock status across trading partners. It serves as the EDIFACT equivalent of the ANSI X12 846 and is widely adopted across retail, manufacturing, and logistics ecosystems. 
 

What Is INVRPT? 

EDIFACT INVRPT is a standardized inventory report message used to communicate stock levels, availability, and inventory status across trading partners. It enables synchronized inventory visibility and supports replenishment, planning, and compliance processes across global supply chains.  
 

Transaction Identity Block 

What Does the EDIFACT INVRPT Do?

The EDIFACT INVRPT (Inventory Report) communicates structured inventory data between trading partners, providing a synchronized view of stock levels, availability, and status across locations. It enables accurate replenishment, demand planning, and compliance reporting by standardizing how inventory balances, ownership, and traceability details are shared across systems. 

EDIFACT INVRPT delivers a network-wide view of inventory by communicating: 

• Stock on hand
• Available vs. reserved or damaged inventory
• Inventory by warehouse, location, or bin
• Batch, lot, serial, or SSCC-level traceability
• Consignment and VMI inventory ownership
• In-transit and future inventory positions  

Organizations rely on INVRPT to synchronize inventory across ERP, WMS, and partner systems while enabling planning, replenishment, and compliance workflows.  

Who Uses the EDIFACT INVRPT?

EDIFACT INVRPT is used by manufacturers, retailers, distributors, and logistics providers to synchronize inventory data across multi-enterprise supply chains. It is critical in environments where inventory is distributed across multiple locations, partners, or ownership models such as consignment or vendor-managed inventory. 

When Is the EDIFACT INVRPT Required? 

INVRPT is required whenever inventory visibility must be shared across trading partners, including after receipts, transfers, adjustments, or during scheduled reporting cycles. It is essential in vendor-managed inventory (VMI), replenishment planning, and multi-location inventory environments. Event-driven and scheduled reporting models often coexist within modern supply chains.  

• On a scheduled basis (daily, weekly, intraday)
• In response to inventory events (receipts, transfers, adjustments)
• Upon request from trading partners
• As part of Vendor Managed Inventory (VMI) programs  

Is the EDIFACT INVRPT Mandated Under Regulation? 

INVRPT is not universally mandated; however: 

• Industry-specific compliance (food, pharma, regulated goods) may require inventory visibility
• Traceability frameworks (lot, batch, expiry tracking) rely on INVRPT-like data structures
• Regulatory reporting often depends on inventory accuracy derived from INVRPT  

How Does INVRPT Work? 

EDIFACT INVRPT works by capturing inventory events such as receipts, transfers, and adjustments, then transmitting standardized inventory data to trading partners. This ensures systems remain synchronized and enables downstream actions such as replenishment, forecasting, and exception management. 

End-to-End Business Workflow 

EDIFACT INVRPT operates as a midstream visibility signal, connecting upstream physical events with downstream planning and replenishment actions. 

Step-by-Step Workflow 

1. Inventory Event Occurs 
   Warehouse activities such as receiving, picking, transferring, or adjusting inventory are recorded in the WMS or ERP.
2. Inventory Data is Captured and Normalized 
   Systems aggregate inventory balances, including stock on hand, reserved, damaged, or in-transit quantities.
3. INVRPT Message is Generated 
   The system produces an EDIFACT INVRPT message reflecting the current inventory position across locations and ownership contexts.
4. Message is Transmitted to Trading Partners 
   INVRPT is sent via EDI or integration platforms to retailers, manufacturers, or distributors.
5. Receiving System Updates Inventory View 
   The receiving partner ingests the INVRPT and updates internal systems for visibility and planning.
6. Downstream Actions are Triggered 
   Replenishment orders, forecasts, or allocation decisions are executed based on updated inventory data.  

Upstream Transactions (Pre-INVRPT) 

Upstream events establish the physical state of inventory before it is reported. 

Downstream Transactions (Post-INVRPT)  

INVRPT drives decision-making and downstream execution. 

Inventory Lifecycle Flow (Execution View) 

Industry-Specific Workflow Variations 

Retail 

Retailers use INVRPT to maintain SKU-level visibility across stores and distribution centers, enabling automated replenishment and allocation. 
 

Manufacturing

Manufacturers rely on INVRPT for raw material availability, production planning, and supplier coordination. 
 

3PL / Logistics 

3PL providers generate INVRPT messages to report inventory on behalf of multiple clients across shared warehouse environments. 
 

Food & Beverage / Pharma 

Regulated industries use INVRPT to track lot, batch, expiry, and quarantine status for compliance and traceability.  
 

Cross-Standard Workflow Mapping 

What triggers an INVRPT message? 

Inventory events such as receipts, transfers, adjustments, or scheduled reporting cycles typically trigger INVRPT messages. 

How often is INVRPT sent? 

INVRPT can be sent in real time, periodically (daily/weekly), or on-demand depending on partner agreements. 

What happens after INVRPT is received? 

Receiving systems update inventory records and trigger replenishment, planning, or exception workflows. 

Is INVRPT part of a continuous workflow? 

Yes, INVRPT operates within a continuous loop of inventory updates, planning, execution, and reconciliation. 

End-to-End Workflow Example 

The EDIFACT INVRPT workflow connects shipment, receipt, inventory reporting, and replenishment into a continuous execution loop. Goods are shipped, received into inventory, reported via INVRPT, consumed by downstream systems, and used to trigger replenishment through orders or forecasts—ensuring synchronized, data-driven supply chain operations. 
 

Goods shipped via DESADV

Shipment data is transmitted to the receiving party, establishing inbound inventory expectations. 
 

Warehouse receives and records inventory 

Physical goods are received, validated, and recorded in WMS/ERP systems, updating stock positions. 
 

INVRPT generated to report stock position 

Inventory balances, availability, and status are structured into an EDIFACT INVRPT message and shared with trading partners. 
 

Retailer or manufacturer consumes inventory data 

Receiving systems ingest the INVRPT message to update inventory visibility and planning models. 
 

Replenishment triggered via ORDERS or DELFOR 

Updated inventory signals drive automated replenishment, forecasting, and allocation decisions. 
 

Industry-Specific Workflow Variations 

• Retail: Store-level replenishment and allocation
• Manufacturing: Production planning and raw material visibility
• 3PL: Multi-client warehouse reporting
• Food & Beverage: Lot, expiry, and quarantine tracking  

Cross-Standard Canonical Mapping 

EDIFACT INVRPT maps most directly to the ANSI X12 846 (Inventory Inquiry/Advice), with additional alignment to transactions such as 947 (Inventory Adjustment Advice), 856 (ASN), and 861 (Receiving Advice). A complete cross-standard mapping ensures consistent inventory visibility, movement tracking, and replenishment across global trading partner ecosystems. 

Extended Inventory Signal Layer (846 vs 947 vs INVRPT) 

Is there an EDIFACT equivalent for the 947 – Inventory Adjustment Advice? 

No, there is no single, direct EDIFACT equivalent to the X12 947 – Inventory Adjustment Advice. Instead, EDIFACT uses a combination of INVRPT (Inventory Report) with inventory qualifiers (e.g., INV, QTY, STS) and internal warehouse events to represent inventory adjustments, capturing both updated balances and the context behind changes. 

How EDIFACT Handles Inventory Adjustments 

EDIFACT does not separate “inventory state” and “inventory change” as explicitly as X12 does with the 846 vs. 947 model. Instead, it uses a state-plus-context approach:

What Information Is Required in the INVRPT? 

EDIFACT INVRPT requires structured data including message identifiers, reporting dates, party information, product identifiers, and qualified inventory quantities. It also supports location, ownership, and traceability data, ensuring complete and accurate inventory visibility across trading partners. 

What are the core required data elements in INVRPT? 

Core INVRPT data elements include message control (UNH, BGM), reporting dates (DTM), party identification (NAD), product identification (LIN, PIA), and inventory quantities (QTY). Additional contextual data—such as inventory type (INV), location (LOC), and traceability (GIN)—enhances accuracy and usability across supply chain systems.  

INVRPT data requirements reflect a multi-dimensional inventory model, where each quantity is paired with: 

• Identity (product and party)
• Context (inventory type and status)
• Location (warehouse or bin)
• Traceability (batch, lot, serial)  

This structure provides inventory data that is complete, interoperable, and actionable, enabling accurate planning, compliance, and execution across multi-enterprise supply chain environments. 

Quick Segment Reference 

Required Segments 

EDIFACT INVRPT requires a core set of segments to establish message integrity and inventory meaning These segments form the minimum viable dataset required for an actionable inventory report.  

Optional Segments 

Optional segments are often mandatory in practice based on trading partner requirements or industry standards. Optional segments enhance the richness and usability of inventory data: 

Required Identifiers 

INVRPT relies on standardized identifiers to ensure interoperability: 

• Product Identifiers: GTIN, EAN, supplier item numbers
• Party Identifiers: Supplier, warehouse, reporting entity
• Location Identifiers: Warehouse codes, GLNs
• Traceability Identifiers (if applicable): Batch, lot, serial, SSCC  

Required Dates 

• Report Date - Date/time of inventory snapshot (DTM+137)
• Additional Dates - Optional timing for movements or status (DTM+ various qualifiers) 

Required Financial Data (if applicable) 

INVRPT does not typically require financial data; however: 

• Inventory valuation may be derived downstream
• Financial reconciliation processes depend on accurate inventory quantities  

Required Reference Numbers 

Service-Level or Line-Level Detail (if applicable) 

Inventory reporting is line-level by design, where each product is reported individually with its associated inventory quantities and attributes. Each LIN segment represents a distinct product and its associated quantities, identifiers, and context. Aggregate reporting may exist but does not replace line-level detail for execution workflows. 

Summary Table of Key Segments 

What Status and Reason Codes Are Used with the INVRPT? 

EDIFACT INVRPT uses status and reason codes to qualify inventory condition, availability, and movement context. Status indicators—typically conveyed through segments such as STS and INV—identify conditions like available, reserved, damaged, or quarantined stock, while reason codes explain changes such as adjustments, transfers, receipts, or losses. 

Status Codes 

Status codes define the current condition and usability of inventory, enabling downstream systems to interpret how stock can be used operationally. 

Common Inventory Status Codes 

Status values are typically conveyed using the STS (Status) segment and supported by inventory context in the INV segment.  

• Available Inventory ready for sale or use
• Reserved / Allocated Inventory committed to orders
• Damaged Inventory not usable due to damage
• Quarantined Inventory restricted for quality or compliance review
• In-Transit Inventory moving between locations
• On Hold Inventory temporarily unavailable
• Expired / Obsolete Inventory beyond usable lifecycle 

Reason Codes 

Reason codes provide context for inventory changes or conditions, explaining why a specific status or quantity exists. 

Common Reason Codes 

Reason codes ensure that inventory changes are auditable, traceable, and explainable across systems. 

Industry-Specific Code Sets 

Different industries extend status and reason codes to meet operational and regulatory requirements.  Industry-specific codes are often governed by trading partner agreements or companion guides, even within the D.96A standard 

• Food & Beverage Expiry status, shelf-life, quarantine, OSD (Over, Short, Damaged)
• Pharmaceuticals Serialized status, compliance holds, recall flags
• Retail Available-to-promise (ATP), allocation status
• Manufacturing Work-in-progress (WIP), production allocation 

How Status and Reason Codes Work Together 

Status and reason codes operate as a paired data model, a pairing that delivers inventory data that is both descriptive and actionable 

• Status = “What is the condition of the inventory?”
• Reason = “Why is the inventory in that condition?”  

Status and Reason Codes Execution Insight  

Status and reason codes transform INVRPT from a static inventory report into an execution-aware signal: 

• Enable exception management (e.g., damaged or missing stock)
• Support compliance and auditability (traceable inventory conditions)
• Drive automated workflows (replenishment, holds, recalls)
• Improve decision accuracy across planning and fulfillment systems  

Structured status signaling is critical for ensuring that inventory data is interpreted consistently across multi-enterprise environments.
