The Lifecycle of Scenario Data

A scenario persisted in FICO® Xpress Insight can have input data, results data, and file attachments. A scenario is created in an unloaded state with no input data, no results data and no file attachments.
The usual way of transitioning the state of the scenario data is to execute the scenario. There are two types of execution mode:
  1. One which sets the input data. This load type of mode has the clear_input flag set to True. On execution of a scenario with this type of execution mode, any existing input data values will be erased. When the model exits, Xpress Insight will capture and persist the current values of the input data entities.
    Note The built in LOAD execution mode has clear_input=True.
  2. One which sets the result data. This run type of mode has the clear_input flag set to False. On execution of a scenario with this type of execution mode, the input data entities in the model are automatically initialized to their values as stored by Xpress Insight. When the model exits, Xpress Insight will capture and persist the current values of the result entities.
    Note The built in RUN execution mode has clear_input=False.
    Note Existing result data values are erased on any execution mode.
    Note Input entities can be re-captured during a run type execution by setting their update after execution flag to True.
For more on execution modes, see the later topic on Execution Modes.
The result data for a scenario should be consistent with the input data. The system provides three options for how the results data is treated as the input data evolves:
  • On-change—the result data is deleted as soon as an input entity value is modified.
  • On-queue—the results data is flagged as dirty as soon as an input entity value is modified, and deletion of the result data is deferred until the scenario is queued for execution.
  • On-execute—the results data is flagged as dirty as soon as an input entity value is modified, and deletion of the result data is deferred until the scenario begins executing.
