2.3 About Service Segments
For how to use service segments of EDIFACT messages in NACCS, see "Table
14-2-4 Service Segment (Processing Request Message)" and "Table 14-2-5 Service Segment(Process Result Message)."
For messages of the "passenger reservation records report (PNR01)" procedures,
however, the PADIS EDIFACT format is used and the service segment (processing requestmessage) definition is different from the UN EDIFACT format. So use the procedure
specification in this case.
