What are Walmart EDI 856 Requirements?

Definition

Walmart EDI 856 Requirements specify how a Walmart drop-ship vendor communicates shipment details through the 856 Ship Notice/Manifest transaction set. Walmart's current supplier documentation states that the 856 communicates shipment contents and related information such as order references, product descriptions, packaging, carrier information, and shipment configuration. The published specification is for the Walmart.com drop-ship vendor EDI environment. :contentReference[oaicite:0]{index=0}

The 856 is part of a broader EDI workflow rather than an isolated document. Walmart's DSV EDI interface also includes transactions such as the 850 purchase order, 855 purchase order acknowledgment, 846 inventory inquiry/advice, and 997 functional acknowledgment. :contentReference[oaicite:1]{index=1}

How the Walmart EDI 856 Works

The shipment process starts with order information and progresses through fulfillment and shipment preparation. The purchase order establishes the merchandise and order references that the supplier uses when preparing the shipment. The supplier then generates the 856 with information that allows Walmart to associate the physical shipment with the corresponding order.

Walmart's published 856 specification uses a hierarchical structure. The transaction includes a mandatory transaction header, beginning segment, and date/time information, followed by hierarchical shipment detail containing item identification, shipment quantities, purchase-order references, carrier details, and marks and numbers. :contentReference[oaicite:2]{index=2}

Key 856 Data Elements

Walmart's current 856 specification identifies specific segments and usage requirements that suppliers should follow when constructing the transaction. The required structure is important because each segment communicates a particular aspect of the shipment and its relationship to the order. :contentReference[oaicite:3]{index=3}

  • ST: Identifies the beginning of the EDI transaction set and its control number.
  • BSN: Provides the beginning information for the ship notice.
  • DTM: Communicates applicable date and time references.
  • HL: Establishes the hierarchical levels used to organize shipment information.
  • LIN: Identifies the products included in the shipment.
  • SN1: Provides item-level shipment details, including relevant quantities.
  • PRF: Connects shipment information to the applicable purchase order.
  • TD1, TD5, and MAN: Provide carrier, routing, packaging, marks, and shipment identification information.

Packaging, Carrier, and Shipment Hierarchy

The shipment hierarchy is central to an accurate Walmart 856 because a shipment can contain multiple packaging and item relationships. Walmart's specification provides HL loops for organizing the transaction and includes carrier quantity and weight, routing, and marks-and-numbers information. :contentReference[oaicite:4]{index=4}

Suppliers should make sure the EDI structure accurately reflects the physical shipment. Product identifiers, quantities, packaging references, purchase-order numbers, carrier information, and shipment identifiers should remain synchronized between warehouse records and the EDI file.

This relationship is particularly relevant to Drop Ship Inventory, because inventory available for direct supplier fulfillment needs to remain aligned with the orders and shipment information transmitted through connected systems.

ERP Integration and Financial Records

Walmart EDI 856 data typically connects the supplier's warehouse or order-management system with its ERP and finance environment. The shipment notice itself is operational, but its references can support downstream receiving, inventory, invoicing, reconciliation, and financial reporting.

The chart of accounts remains an accounting structure maintained within the ERP rather than an 856 requirement. However, ERP integration can use shipment information as part of workflows that classify inventory, revenue, freight, taxes, or other applicable financial activity.

An EDI Invoice represents structured electronic billing information and can be reconciled against the order and fulfillment records established through the shipment workflow. Maintaining consistent identifiers across these documents supports traceable financial processing.

Connectivity, Validation, and Acknowledgment

Walmart currently documents several EDI connectivity methods for its supplier interface, including AS2, VAN, SFTP, and solution-provider connections. For production EDI over SFTP, Walmart specifies a file naming convention containing the DSV identifier, creation date, creation time, and sequence information. Walmart also defines segment, element, and field delimiters for its EDI files. :contentReference[oaicite:5]{index=5}

The 997 Functional Acknowledgment provides control information about the syntactical analysis of electronically encoded EDI documents. Suppliers should monitor acknowledgments as part of their transaction-control process and maintain records linking acknowledgments to transmitted files. :contentReference[oaicite:6]{index=6}

For broader compliance education, Government Contract Management Software: Guide explains the features, compliance requirements, and selection considerations relevant to government contract management software; that subject is separate from Walmart's 856 specification but illustrates how structured compliance requirements can be incorporated into business processes.

Tax and Financial Workflow Considerations

Shipment information can contribute to downstream tax validation because ship-from and ship-to locations may affect jurisdiction rules, exemptions, nexus, and applicable tax treatment. For drop-ship transactions, suppliers should validate the relevant transaction locations before applying tax treatment, including potential use tax considerations.

An EDI Tax Filing workflow can use structured transaction information alongside applicable jurisdictional rules and tax records to support reporting and reconciliation. The 856 does not itself determine the tax obligation, but accurate shipment data can provide supporting information for downstream tax processes.

An EDI Payment File belongs to the payment workflow rather than the shipment notice, but consistent order and shipment references can help connect fulfilled transactions with invoices, approved amounts, and subsequent payment records.

Best Practices for Walmart EDI 856

  • Use Walmart's current 856 specification as the authoritative source for segment requirements, field usage, and transaction structure.
  • Map purchase-order, product, quantity, packaging, carrier, and shipment identifiers consistently across ERP, warehouse, and EDI systems.
  • Validate the 856 against the actual shipment before transmission.
  • Maintain hierarchical relationships between shipments, orders, packaging units, and items.
  • Monitor 997 acknowledgments and retain transaction records for reconciliation and operational reporting.
  • Keep connectivity settings, file naming conventions, delimiters, and supplier-specific implementation details aligned with Walmart's current documentation.

Summary

Walmart EDI 856 Requirements define the structure and shipment information suppliers use to transmit a Ship Notice/Manifest to Walmart.com in the DSV EDI environment. The transaction connects purchase orders with products, quantities, packaging, carrier information, and shipment configuration. Accurate hierarchy, identifiers, ERP integration, connectivity settings, and acknowledgment controls support reliable fulfillment, reconciliation, vendor management, and financial reporting. :contentReference[oaicite:7]{index=7}
