Function: missingRequiredLoop()

missingRequiredLoop(position, loop): X12ParseWarning

Build an X12_MISSING_REQUIRED_LOOP warning. Emitted when a TR3-required loop is structurally absent (e.g. no Loop 2010BB Payer Name inside a Subscriber HL). The parser does not enforce situational rules: only loops marked usage: "required" in the loop spec fire this warning, so the loop id and its rationale are both library constants.

Parameters​

position​

X12Position

loop​

X12RequiredLoop

Returns​

X12ParseWarning

Example​

import { missingRequiredLoop, REQUIRED_LOOPS } from "@cosyte/x12";
const w = missingRequiredLoop(
  { segmentIndex: 12, groupIndex: 0, transactionIndex: 0 },
  REQUIRED_LOOPS.PAYER_NAME_2010BB,
);
