Steps
Map the shipment order data to the EDI 204 transaction set segments: B2/B2A (shipment information), L11 (reference numbers), G62 (dates), N1/N3/N4 (name and address loops), S5/L11/G62/N1 (stop detail loops), and OID (order information)
Validate the 204 against the carrier's implementation guide before transmission, checking mandatory segments, element lengths, and code list values
Transmit the 204 via your EDI connection (AS2, SFTP, or Stedi API-based EDI) to the carrier's interchange
Receive and parse the 990 Motor Carrier Freight Details and Invoice response, checking the Response Code element for 'A' (accepted) or 'D' (rejected with reason code)
If rejected, evaluate the reason code, adjust the tender terms or carrier selection, and retransmit or cancel the load in the TMS accordingly
Known gotchas
The 990 must be returned within the carrier's contractual response window (often 2-4 hours); silence does not imply acceptance and can leave a load uncovered
Carrier implementation guides frequently add Z-segment or custom loop requirements on top of the base X12 standard; always onboard against the carrier-specific guide
ISA/GS envelope control numbers must be unique per sender-receiver pair and increment correctly; reusing a control number causes duplicate rejection
