The OCT is created when you create an Contact Optimization session. When you run an
Contact Optimization session,
Contact Optimization analyzes the PCT (populated by
Campaign) using the optimization rules and constraints you configured.
Contact Optimization populates the OCT with optimized contacts and their associated offers during this process.
Campaign then retrieves the results from the OCT for use in a marketing campaign. The OCT is composed of a subset of the PCT fields, and a field for the score that is used for optimization (that is, the score that is being maximized).
