Article Link: https://help.truecommerce.com/en/articles/13214674-trading-partner-onboarding-core-mark-us
If you are looking to implement Core-Mark US 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
Core-Mark US 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 Core-Mark US:
X12 Qualifier | EDI ID | Primary ID? |
08 | 9257910035 | Yes |
08 | 9257910021 | No |
ZZ | TST1COREMARKXXX | No |
ZZ | PFGCOREMARK | No |
Core-Mark US 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 Core-Mark US to determine the proper EDI ID to use.
