Routing Envelope


The EASI Routing Envelope is used within each EASI electronic transmission to uniquely identify the specific transmission. The Routing Envelope consists of a header segment identifying origin and destination information and a trailer segment identifying the end of the transmission. 

The Routing Envelope functions as the Interchange Control Header/Footer, 'wrapping' the edi transaction set.

Every transmitted EDI transaction document must include a valid routing envelope.

The Routing Envelope makes it possible to have multiple sets of records within each file transmission. However, all sets of records within a single transmission must be of the same type (ex: 856 ASN, 850, etc).
