Handling Unit 

Definition

A handling unit is a physical object representing a specific vehicle for which activities are planned and executed in the yard.   

                                            

Use

YM utilizes the handling unit (HU) to represent a vehicle in the yard. In addition, for each delivery assigned to a vehicle, the system automatically creates a “logical” HU as a lower-level HU to the “vehicle” HU.

Since vehicles cannot contain deliveries (they can only contain other HUs or materials), the system creates logical HUs with the relevant delivery number in each HU’s header, in order to keep track of the deliveries assigned to a vehicle.

HUs in YM are an extension of the existing HU concept in Handling Unit Management (LO-HU). For more information on the general definition, structure and use of handling units, see Handling Unit.

You can view the detailed HU data for a vehicle, including hierarchical display of HUs and the deliveries contained in the logical HUs, via the Display HU details monitor method. For more information, see Yard Monitor Methods.

 

Structure

In addition to the normal HU attributes, an HU in YM consists of the following attributes (in HU header):

·        Yard

·        Transport equipment stock status

·        Sealing number

·        Blocking indicator and reason code

·        Door and staging area

·        Urgency (for cross-docking purposes)

·        Reference document information required for scheduling

·        Location and location class

·        Container ID

·        Forwarding agent, owner and transponder information

Handling units can comprise of lower level handling units.
