Trading Partner: WB Mason
If you are looking to implement WB Mason as a new Trading Partner within your 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
WB Mason utilizes the following Electronic Data Interface (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 EDI transaction that is sent or received.
Below is a list of the most common EDI IDs typically used by WB Mason:
X12 Qualifier | EDI ID | Primary ID? |
ZZ | WBMASON | Yes |
ZZ | WBMASONT | No |
WB Mason 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 WB Mason to determine the proper EDI ID to use.
Preliminary Steps
WB Mason requires that new vendors request to setup an EDI relationship via their vendor portal. Within their vendor portal, is a Trading Partner Contact Information form that must be filled out and submitted to begin the EDI Setup process.
Direct Trading Partner Testing
WB Mason hosts testing directly with their team and requires that compliance testing be completed prior to go-live. Your TrueCommerce Implementation Specialist can help with the onboarding and testing process.
