Item availability calculations use the following assumptions:

When the item availability check is done on an assembly, all existing orders for the assembly are reviewed. NetSuite does not review possible component shortages of components.

The current item availability check is available only for assembly and inventory items.

Existing drop ship orders and special orders are not considered as part of supply or demand.

Recommended purchases or work orders in a supply plan are not considered for availability calculations because these orders are not yet firmed.
