Component rule on IEA segment

This documentation describes the component rule for the IEA segment.

The IEA Segment component of an interchange has the following component rule:


InterchangeCtrl# Element:$ =
InterchangeCtrl# Element:.:Partner Inbound ISA Segment Control 
ANSI & #InclFunct'lGroups Element:$-COUNTABS (Inbound Partner 
Funct'lGroup ANSI)

The component rule states that the InterchangeCtrl# Element of the IEA Segment must be the same as the InterchangeCtrl# Element of the ISA Segment. If an Inbound Partner Funct'lGroup is invalid and a restart occurs, the component rule keeps different interchanges from being mixed up with one another.
