Setting Up a Product Structure
Define product structures in Product Structure Maintenance (13.5).
Important fields include the following.
Qty Per. Specify how much of this component is needed to make the
parent item. In discrete manufacturing, items are made in individual
units, and the component quantity is the amount needed for a single
unit of a parent product. For example, two screws are required for one
pair of sunglass frames.
In process manufacturing, products are made in batches and the
component quantity per parent on a formula or recipe is stated with
respect to a batch quantity for the parent product. Since the only
economical way to coat lenses is in batches, the amount of a
particular coating might be specified for a batch of several hundred
lenses.
Reference. On a complex assembly that contains many components,
an item may appear several times on the same drawing and product
structure. Use Reference to identify a component that appears
multiple times on the same parts list.
The reference code can be a drawing reference number that helps to
relate a component to a specific position on a drawing, or a code
associated with an engineering change order or an engineering change
notice. The system uses parent, component, reference, and start date
to define a unique product structure record. A component can have
