Trading Partner: Winco
If you are looking to implement Winco Foods as a new Trading Partner within your Electronic Data Interchange (EDI) network, this article will provide you with an understanding of the requirements, preliminary and next steps, as well as commonly used transaction types.
EDI IDs
Winco Foods utilizes the following EDI IDs for identification purposes. These EDI IDs are made up of a Qualifier and an ID which will be sent within their Interchange Control Header, ISA segment, on your inbound transactions. This allows Transaction Manager to be able to identify the Sender and Receiver of any sent/received EDI transaction.
The table, below, lists the most common EDI IDs used by Winco Foods.
X12 Qualifier | EDI ID | Primary ID |
08 | 5035816100 | Yes |
08 | WAREUSB | No |
08 | WAREUSBTST | No |
Winco Foods will expect a specific EDI ID based on your business relationship with them. Selecting the wrong EDI ID will result in EDI Transactions not being sent or received.
You will need to work with Winco Foods to determine the proper EDI ID to use.
