Segment Descriptions: 

ISA/IEA - The ISA/IEA envelope, hereafter referred to as the "transmission envelope", isolates one group of transmitted data from another. Several dissimilar types of business documents can be "stacked" one "behind" another in an "interchange envelope". Each "interchange envelope" is identified by its own control number. This number should be sequential between transmission partners and can be used for statistical control, audit control, and error recovery information. The version of the "interchange envelope" is contained in the ISA segment. This allows the computer to analyze and process different versions of the same enveloping transmission standard.

GS/GE - The GS/GE envelope isolates one group of similar business documents from another. Several dissimilar types of business documents can be "stacked" one "behind" another in a "interchange envelope", each group in its own GS/GE envelope. A count is kept of the number of groups of business documents (GS/GE segments) "stacked" together in an "interchange envelope" and is placed in the IEA01 elements. Each GS/GE envelope is identified by its own control number within the "interchange envelope" number. The type of business transactions contained within the GS/GE envelope is indentified in the GS segment. This segment also identifies the "version level" of the transaction, data dictionary, and segment directory to be used to interpret the transmission. The use of separate GS/GE envelopes allows for several different versions of transaction sets to be communicated within the same "interchange envelope". In a distributed processing or similar environment, the "front-end" EDI software would open the "interchange envelope", validate the sender/receiver, validate the transmission for conformance with the standards, identify each GS/GE envelope and, if acceptable, send it to the proper function to handle that type of transmitted data, i.e. purchasing, order entry, scheduling, accounts payable or accounts receivable. These are commonly referred to as functional groups.

ST/SE - The ST/SE envelope isolates one business document from another. Several of the same type of business documents can be "stacked" on "behind" another, each in their own ST/SE envelope. A count is kept of the number of business documents (ST/SE segments) "stacked" together ina GS/GE envelope and is placed in GE01. Each ST/SE envelope is identified by its own control number within the GS/GE envelope number for audit trail purposes.
