Features of EDI 837P- Part II


Functional Group:
A Functional Group consists of one or more related Transaction Sets sharing the same Functional Group ID. Functional Group is like an envelope for Transaction Sets that starts with a GS (Functional Group Header) segment and ends with a GE (Functional Group Trailer) segment.

Sample GS:
GS*HC*99999999999*888888888888*20111219*1340*1377*X*005010X222A1~

Sample GS:
GE*1*1377~

GS06 (Group Control Number) and GE02(Group Control Number) must match

Transaction Set:
A Transaction Set  consists of  one or more data segments conveyed between trading partners. It usually represents a business document. Transaction Sets are defined in the X12 standard with a number and name, a statement of purpose, a Functional Group ID, and a table listing the included segments, their position numbers, requirement designation, maximum usage, and loop repeat counts. Transaction Sets start with an ST (Transaction Set Header) segment and end with an SE (Transaction Set Trailer) segment.

Sample ST:
ST*837*0001*005010X222A1~

Sample SE:
SE*39*0001~

ST02(Transaction set control number) and SE02(Transaction Set Control Number) must match.

Loops:

A loop is a set of mutually related segments in a Transaction Set. Segments are grouped together in this way so that it  conveniently represent a block of related information.
