Complex flows

Complex flows are transaction flows that don't follow a straightforward order-to-cash path where a business process starts from one milestone and goes through the rest without any bumps or detours.

A couple of examples of complex flows are when an order has goods destined for multiple locations, or when multiple orders are consolidated into a single shipment.

In general, complex flows may include rejections, cancellations, incomplete milestones, missing milestones, milestones associated with multiple other milestones, and so on. So really, most of your transaction flows will probably be complex flows.
