Instance of a Reusable or Nonreusable Product
Representation Reference
By default, a representation reference is defined as
"nonreusable" and can have only one instance. To create several instances of a
representation reference, this representation reference must be defined as
"reusable" (this operation is irreversible). For more information, see Representation Reference. A product representation instance has a specific behavior: it can be associated with
both reusable and nonreusable representation reference.
