Electronic Data Interchange
Electronic data interchange (EDI) is the paperless exchange of trading documents such as purchase orders, shipment authorizations, advance ship notices, and invoices using standardized document formats. You can use EDI eCommerce features to communicate EMT documents automatically among multiple levels of suppliers.
Note: If you are using standard EMT, in which there is a two-level relationship between the organization recording the final customer’s demand and its supplier, EDI transmission is optional. For example, you can fax or mail the EMT purchase order to the SBU. EDI is required for the other automated processing features offered by EMT.
However, if you use multilevel EMT, in which there are two or more organizational levels in addition to the final supplier, EDI is required.
