Calculating Tier Demands of Virtual Locations for Consolidated Ordering
(VLCO)
If there is a virtual location for consolidated ordering on level n (n ≥2) of the BOD, the system adds all tier demands of locations in the sub-trees below the consolidated locations to the tier demands of the VLCO.

The graphic above shows a VLCO that consolidates two locations. The tier demands of the sub-trees below locations Child 1 and Child 2 are treated as tier demands of the sub-tree below the VLCO. The tier demands that belong to the VLCO are calculated in the same way as in the case of a normal location.
