846 Inventory Inquiry/Advice

Functional Group IB

X12M Supply Chain Subcommittee

This X12 Transaction Set contains the format and establishes the data contents of the Inventory Inquiry/Advice Transaction Set (846) for use within the context of an Electronic Data Interchange (EDI) environment. The transaction set can be used in the following ways: (1) for a seller of goods and services to provide inventory information to a prospective purchaser, with no obligation to the purchaser to acquire these goods or services; (2) for a representative of a seller of goods and services to supply inventory information to that seller; (3) for one location to supply another location with inventory information; and (4) for an inquiry as to the availability of inventory with no obligation on the seller of goods and services to reserve that inventory.

What is an EDI 846?

An EDI 846 Inventory Inquiry/Advice communicates product inventory levels from a supplier to a buyer. It contains information about product location (SDQ segment), quantity levels (QTY segment), and estimated replenishment dates (DTM segment).

How is an EDI 846 used?

For example, Vendor A sends Retailer B an EDI 846 Inventory Inquiry/Advice twice daily to provide an indication of their entire catalog's stock status. If Vendor A communicates that a SKU is out of stock in the EDI 846 Inventory Inquiry Advice, Retailer B will take that SKU off the website or list the item as “out of stock” until a subsequent EDI 846 Inventory Inquiry/Advice shows that it is available.
