TrnSegment

TrnSegment models the X12 TRN trace-number segment, used in 835/837 transactions to carry a trace number (e.g. a payment/check number or claim trace identifier) that lets the receiver correlate the transaction back to the sender's originating record. Its two optional trailing elements are written only when populated (BR-059).

Purpose

• Represents the TRN segment identity via SegmentId returning the literal "TRN" (BR-020).
• Carries TraceTypeCode classifying the trace, paired with CurrentTransactionTraceNumbers, the trace number value itself.
• Writes OriginatingCompanyIdentifier (TRN03) and ReferenceIdentification (TRN04) on Build() only when they are non-empty (BR-059).

Context

• Namespace: SAIF.Common.Files.Edi.Segments
• Assembly/package: SAIF.Framework.Common.Files

Public members

Member	Signature	Purpose
SegmentId	string SegmentId { get; }	Returns the literal X12 segment identifier "TRN".
TraceTypeCode	string TraceTypeCode { get; set; }	The trace-type qualifier code (TRN01), element 1.
CurrentTransactionTraceNumbers	string CurrentTransactionTraceNumbers { get; set; }	The trace number value (TRN02), element 2.
OriginatingCompanyIdentifier	string OriginatingCompanyIdentifier { get; set; }	The originating company's identifier (TRN03), written on Build() only when non-empty (BR-059).
ReferenceIdentification	string ReferenceIdentification { get; set; }	An additional reference identifier for the trace (TRN04), written on Build() only when non-empty (BR-059).
Build	IEdiSegment Build()	Creates a SegmentBuilder("TRN"), adds TraceTypeCode and CurrentTransactionTraceNumbers at elements 1-2 unconditionally, and adds OriginatingCompanyIdentifier/ReferenceIdentification at elements 3-4 only when non-empty, returning the built segment (BR-059).
Fill	void Fill(IEdiSegment segment)	Reads elements 1-4 via GetChildValue into TraceTypeCode, CurrentTransactionTraceNumbers, OriginatingCompanyIdentifier, and ReferenceIdentification.
Parse	static TrnSegment Parse(IEdiSegment segment)	Instantiates a new TrnSegment, calls Fill(segment) on it, and returns it.
