Table	Production.BillOfMaterials
Description	Items required to make bicycles and bicycle subassemblies. It identifies the heirarchical relationship between a parent product and its components.

Columns

Column	Data Type	Nullable	Default	Description
BillOfMaterialsID	int	not null		Primary key for BillOfMaterials records.
ProductAssemblyID	int	null		Parent product identification number. Foreign key to Product.ProductID.
ComponentID	int	not null		Component identification number. Foreign key to Product.ProductID.
StartDate	datetime	not null	(getdate())	Date the component started being used in the assembly item.
EndDate	datetime	null		Date the component stopped being used in the assembly item.
UnitMeasureCode	nchar(3)	not null		Standard code identifying the unit of measure for the quantity.
BOMLevel	smallint	not null		Indicates the depth the component is from its parent (AssemblyID).
PerAssemblyQty	decimal(8, 2)	not null	((1.00))	Quantity of the component needed to create the assembly.
ModifiedDate	datetime	not null	(getdate())	Date and time the record was last updated.
