Interface: Ta1Segment

A decoded envelope-level TA1 Interchange Acknowledgment segment. TA1 is NOT a transaction set - per the ASC X12 standard it lives at the envelope level, between ISA and the first GS, or alone inside an ISA..IEA with no GS at all (a TA1-only interchange). One interchange may carry multiple TA1 segments, each acknowledging a prior inbound interchange.

elements[0] = "TA1"; elements[1] = TA1-01 (echoes the prior interchange's ISA-13 control number); elements[2] = TA1-02 (interchange date YYMMDD, echoes ISA-09); elements[3] = TA1-03 (interchange time HHMM, echoes ISA-10); elements[4] = TA1-04 (Interchange Acknowledgment Code, code list I13: A accepted, E accepted with errors, R rejected); elements[5] = TA1-05 (Interchange Note Code, code list I18, 000–028+).

The Phase 3 envelope walker captures TA1 segments here verbatim; the typed-ack model is built on top by parseTA1. TA1 contains only structural control / disposition codes - by spec it carries NO PHI.

Example

import type { Ta1Segment } from "@cosyte/x12";
declare const ta1: Ta1Segment;
ta1.elements[1]; // TA1-01 - echoes inbound ISA-13
ta1.elements[4]; // TA1-04 - "A" | "E" | "R"
