Process EDI 214 carrier shipment status messages into a tracking pipeline

Steps

1. Receive the EDI 214 (Transportation Carrier Shipment Status Message) from the carrier via AS2, SFTP, or VAT/EDI network; parse the ISA/GS envelope to identify the sender and interchange control number.
2. Extract the B10 segment for the shipment identifier (PRO/BOL number, shipment ID), then iterate over AT7 segments which carry the status code, date, time, and reason code.
3. Map the AT7 status and reason codes to your internal unified tracking state machine — carrier-specific code lists vary, so maintain a carrier-keyed lookup table rather than hardcoding values.
4. Upsert the status event into your tracking store keyed on (shipment_id, event_timestamp, status_code) to ensure idempotency; the same 214 may be retransmitted.
5. Emit downstream events (order management update, customer notification trigger) only after deduplication and sequence validation — compare incoming event timestamp to the latest stored event to prevent out-of-order status regression.
6. Send an EDI 997 functional acknowledgment back to the carrier within the agreed interchange SLA to confirm receipt and prevent retransmission storms.
