EWM Yard Management: Check-In, Yard Bin, Door Assignment and Check-Out
Before goods are unloaded, the truck itself is managed: it is checked in at the gate as a transportation unit, parked in a yard bin while the doors are busy, moved to a free door, unloaded and received, then checked out.

01Check-in at the gate
The truck arrives; the gate keeper checks it in. Transportation unit TU-0000801 is linked to inbound delivery 180000900.
Business scenario
A supplier truck with 100 EA of RM-1000 arrives at 08:00. All inbound doors are busy until 09:30.
All companies, numbers and documents are fictional demo data.
Step-by-step flow
- 01
Check-in at the gate open in twin
The truck arrives; the gate keeper checks it in. Transportation unit TU-0000801 is linked to inbound delivery 180000900.
From now on the warehouse can see the truck, its deliveries and how long it waits.
- 02
All doors are busy open in twin
No inbound door is free until 09:30. Where does the truck go?
The system knows exactly which truck is where.
- 03
Invisible waiting trucks open in twin
Trucks queuing outside are invisible to the system: no planned door assignment, no waiting-time record, and blocked public roads.
Demurrage charges and missed slots usually start here.
- 04
Park in the yard open in twin
A yard movement places TU-0000801 in yard bin YARD-01.
Supervisors see the yard in the warehouse monitor.
- 05
Move to door 01 and unload open in twin
At 09:30 door 01 is free. The TU docks, is unloaded, and goods receipt is posted: +100 EA.
From here the inbound process continues as usual (putaway).
- 06
Check-out open in twin
The empty truck leaves through the checkpoint; the TU is checked out with its times recorded.
Arrival, waiting, docking and departure times are available for carrier and door performance analysis.
- 07
Yard visit complete open in twin
Check-in → yard → door → unload → check-out.
Yard management connects transportation with warehouse operations.

Interview questions
What is a transportation unit in EWM?
The smallest loadable unit of a vehicle (e.g. a truck or trailer) as seen by the warehouse. Deliveries are assigned to it; it is checked in and out at checkpoints, moved through yard bins and docked at doors, recording times along the way.
