EDI IDs
Patterson Companies 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 Patterson Companies:
X12 Qualifier | EDI ID | Primary ID? |
ZZ | PCOO | Yes |
ZZ | PCOL | No |
ZZ | PCOOTEST | No |
ZZ | PCOLTEST | No |
Patterson Companies 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 Patterson Companies to determine the proper EDI ID to use.
