Event Log

The Event Log is the complete audit trail for every order and purchase order in your OMS. It records every system action, status change, and communication with external systems.

Use this log to track progress, diagnose issues, understand automation, and resolve discrepancies.

OMS Status is the high-level summary of the order's current state (e.g., Warehouse Processing).
Event Type/Sub-Type are the specific, detailed actions that occur, often many within a single status phase.

For example, an order with an OMS Status of Warehouse Processing can have events for being sent to the warehouse, received by the warehouse, and fulfilled by the warehouse, all before the status finally changes to Shipped.
