conform to…

Envelope Segments
EDI transactions are surrounded by
6 envelope segments. These
segments contain important
routing information, such as ids,
version, and transaction type.
ISA/IEA – Interchange Envelope
Contains an entire transmission
GS/GE – Group Envelope
Contains one group of similar
transactions (e.g., multiple purchase
orders)
ST/SE – Transaction Set Envelope
Contains data that describes one single
transaction (e.g., one pay order)

Reading a segment of data
BIG*20020123*367498**PX02-0000000081**00*DI
Segment Identifer
First few characters of each segment
BIG
Element Delimiter
Separates each field in a segment
*
Empty Field
Field in which no data was sent; results **
in an error when that field is required
Qualifier
Often a two or three digit code that is
meant to describe another field
DI
Other key pieces of information found in this specific example are purchase
order number, invoice number, and invoice date.
