What does a delivery schedule adjustment look like as environment state?

A wholesale distributor holds order ORD-7714 for a retail chain: four staged deliveries, DEL-1 to DEL-4, each to a different store group, with an invoice milestone tied to each delivery.

The regional depot that was due to fulfil DEL-2 and DEL-3 closes for a week. A dispatcher, or the agent acting as one, is asked to rebuild the schedule.

The starting state includes the four delivery lines with quantities and windows, stock reservations RSV-310 and RSV-311 at the closed depot, a customer clause allowing one rescheduling without penalty, and invoice milestones INV-M2 and INV-M3 triggered on delivery.

The correct action moves DEL-2 and DEL-3 to a second depot, releases the old reservations, creates new ones, and shifts both invoice milestones to follow the new dates. It also checks the penalty-free clause and records that it has now been used.

If the agent changes only the dates, stock stays reserved at a closed site, invoices are raised before goods arrive, and a second rescheduling request would wrongly be treated as penalty-free.

**What it teaches:** a task pack can carry quantities, locations, billing triggers and contract clauses together. The grader checks that every linked record moved with the delivery and that the clause counter changed.
