Trading Partner: McKesson Drug


If you are looking to implement McKesson Drug 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

McKesson Drug 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 McKesson Drug:
