Understanding EDI 846: The Inventory Inquiry/Advice Document

In the world of electronic data interchange (EDI), businesses rely on standardized documents to streamline operations and communicate efficiently. One of these critical documents is the EDI 846, also known as the Inventory Inquiry/Advice. This blog post will break down what the EDI 846 is, how it’s used, and the key segments that make it work—using simple terms anyone can understand.

What is the EDI 846?

The EDI 846 is an electronic message used by a supplier to share information about their inventory levels with their trading partners, such as retailers or distributors. Think of it as a digital snapshot of what’s in stock. It helps businesses avoid issues like overselling (when an item is out of stock) or underselling (when stock is available, but nobody knows about it).

How is the EDI 846 Used?

The EDI 846 plays a vital role in inventory management and business relationships. Here’s how businesses typically use it:

Suppliers to Retailers: A supplier sends an 846 document to a retailer to inform them about what products are in stock, quantities available, and any changes to inventory levels. This allows retailers to manage their orders efficiently.
Dropshipping Scenarios: If a supplier ships directly to customers on behalf of a retailer, the EDI 846 ensures the retailer knows what’s available to sell in real-time.
Automating Inventory Management: Retailers can integrate the EDI 846 into their systems to automatically update inventory, reducing manual work and errors.

For example, a Jeep accessory supplier might send an EDI 846 to a retailer, providing real-time updates on how many spare tire covers are in stock, their sizes, and availability.

Important Segments of the EDI 846

The EDI 846 is made up of specific data segments, each serving a unique purpose. These segments help organize inventory data in a way that systems can understand and process. Here are the most important ones:

Header Segment (ST, BIA)
- ST (Transaction Set Header): Identifies the document as an EDI 846 and assigns a control number for tracking.
- BIA (Beginning Segment for Inventory): Provides the purpose of the document (e.g., inventory status update) and key reference details like the creation date.
Item Detail (LIN)
- LIN (Item Identification): Lists the item’s unique identifier, such as a UPC or SKU. This ensures the retailer knows exactly which product is being referenced.
Quantity Information (QTY)
- QTY (Quantity): Specifies the amount of stock available. It might also include data on committed inventory (what’s already promised to other orders).
Product/Location Details (PID, REF, N1)
- PID (Product/Item Description): Provides a brief description of the item, like “Black Jeep Wrangler Spare Tire Cover, 32 inches.”
- REF (Reference Information): Adds additional details such as a warehouse ID or product model.
- N1 (Name): Identifies the sender (supplier) and receiver (retailer) of the document.
Summary (CTT, SE)
- CTT (Transaction Totals): Gives a summary, such as the total number of items listed in the document.
- SE (Transaction Set Trailer): Marks the end of the document and ensures all data is accounted for.

How Does the EDI 846 Work in Practice?

Let’s imagine you’re a retailer selling Jeep spare tire covers. Your supplier sends an EDI 846 with the following details:

SKU: 12345
Description: "Black Jeep Wrangler Spare Tire Cover, 32 inches"
Available Quantity: 50
Warehouse: TX-01

Your system automatically updates to show 50 units available for customers to order. If a customer buys one, your inventory is adjusted to reflect the sale in real-time. This prevents overselling and keeps customers happy with accurate stock information.
