Lower Level Structure
The lower level of the product structure includes the physical assemblies, component parts, and standard parts that go into the design and manufacturing of the product. These objects represent the actual physical parts that you design, purchase, and manufacture, as well as the services for the products that are delivered to the customer.
The lower level of the product structure is flexibly designed to accommodate the varied purposes of any site and any type of product. Specifically, the organization of the objects within the lower level of the product structure can be defined according to any hierarchical or other relationship requirements.
Lower-Level Objects and Structure Example
Although WADM configuration management includes a base lower-level object type that can be used out of the box, you can create any number of lower-level object types and define any configuration of parent-child relationships between them.
For example, in the diagram below, the following objects are defined for the lower level of a product:
Assembly—An assembly is the highest level object of the lower-level product structure. Only an assembly can be the child of a design solution from the configuration level. An assembly can have a child with an object type of Assembly, Component Part, or Standard Part.
Component Part and Standard Part—These objects can only be the child of an assembly and no other object type.
