Electronic Data Interchange

Many libraries use Electronic Data Interchange (EDI) accounts to send purchase orders and receive invoices from providers electronically. In Evergreen users can setup EDI accounts and manage EDI messages in the admin module. EDI messages and notes can be viewed in the acquisitions module. See also the EDI Installation Instructions because this is required for use of EDI.

Entering SANs (Standard Address Numbers)

For EDI to work your library must have a SAN and each of your providers must each supply you with their SAN.

A SAN (Standard Address Number) is a unique 7 digit number that identifies your library.

Entering a Library’s SAN

These steps only need to be done once per library.

  1. In Evergreen select AdminServer AdministrationOrganizational Units
  2. Find your library in the tree on the left side of the page and click on it to open the settings.


    Multi-branch library systems will see an entry for each branch but should select their system’s top organization unit.

  3. Click on the Address tab.
  4. Click on the Mailing Address tab.
  5. Enter your library’s SAN in the field labeled SAN.
  6. Click Save.
Enter Library SAN

Entering a Provider’s SAN

These steps need to be repeated for every provider with which EDI is used.

  1. In Evergreen select AdminServer AdministrationAcquisitionsProviders.
  2. Click the hyperlinked name of the provider you would like to edit.
Enter Provider SAN
  1. Enter your provider’s SAN in the field labeled SAN.
  2. Click Save.
Enter Provider SAN

Create an EDI Account


You must create your provider before you create an EDI account for the provider.

  1. Contact your provider requesting the following information:

    • Host
    • Username
    • Password
    • Path
    • Incoming Directory
    • Provider’s SAN
  2. In Evergreen select AdminServer AdministrationAcquisitionsEDI Accounts.
  3. Click New Account. A pop-up will appear.
Create EDI Account
  1. Fill in the following fields:

    • In the Label field, enter a name for the EDI account.
    • In the Host field, enter the requisite FTP or SCP information supplied by your provider. Be sure to include the protocol (e.g. ftp://ftp.vendorname.com)
    • In the Username field, enter the username supplied by your provider.
    • In the Password field, enter the password supplied by your provider.
    • Select your library as the Owner from the drop down menu. Multi-branch libraries should select their top level organizational unit.
    • The Last Activity updates automatically with any inbound or outbound communication.
    • In the Provider field, enter the code used in Evergreen for your provider.
    • In the Path field, enter the path supplied by your provider. The path indicates a directory on the provider’s server where Evergreen will deposit its outgoing order files.


      If your vendor requests a specific file extension for EDI purchase orders, such as .ord, enter the name of the directory, followed by a slash, followed by an asterisk, followed by a period, followed by the extension. For example, if the vendor requests that EDI purchase orders be sent to a directory called in with the file extension .ord, your path would be in/*.ord.

    • In the Incoming Directory field, enter the incoming directory supplied by your provider. This indicates the directory on the vendor’s server where Evergreen will retrieve incoming order responses and invoices.


      Don’t worry if your incoming directory is named out or outgoing. From your vendor’s perspective, this directory is outgoing, because it contains files that the vendor is sending to Evergreen. However, from Evergreen’s perspective, these files are incoming.

EDI Messages

The EDI Messages screen displays all incoming and outgoing messages between the library and its providers. To see details of a particular EDI message, including the raw EDIFACT message, double click on a message entry. To find a specific EDI message, the Filter options can be useful. Outside the Admin interface, EDI messages that pertain to a specific purchase order can be viewed from the purchase order interface (See Acquisitions → Purchase Orders).
