The three data sets that must sync
Three data sets need to stay in step across your customs, TMS and ERP stack. Shipment level customs status. Guarantee usage and remaining headroom. Proof of arrival and discharge for every transit movement.
If any one of them drifts, the audit trail falls apart.
Mapping T1 and T2 to your data model
Model the declaration type as an attribute of the consignment, not the shipment. A single trailer can carry both T1 and T2 consignments. Store the Union status evidence at the consignment level too, so the audit trail is intact if the goods are separated later. The T1 and T2 transit document guide illustrates why the consignment is the right unit.
Keep the discharge signal flowing back
The most overlooked integration point is the return leg. Once the destination office discharges the movement, that signal has to write back into the TMS and ERP so the guarantee headroom is released and the audit trail is closed.
