Update shipment processing dates and set delay type on shipments

Unclear shipment processing dates and delay types cause scheduling conflicts and missed pickups. Provide accurate ready dates and delay categories so fulfillment teams dispatch on time.

Overview

Unclear or missing shipment processing dates create avoidable scheduling friction for fulfillment coordinators and dispatch teams. This flow applies order-item rules to assign delay types and compute ready-by datetimes so dispatchers get consistent, actionable dates within minutes of shipment creation.
