Calling the ATT forecast engine with SMP measure

This section provides an overview of the required conditions to call the forecast engines, and to generate forecasts for the selected item and location, when the CallForecastEngine command is used.

• When the engine is of the type ATT and the SMP measure is defined:
  • checks the value of the SMP measure for each item and location combination.
  • The SMP measure at PCONST > 0, calls the engine using the CROSTONS (fitModelGivenAlgorithm, algorithm=CROSTONS) algorithm, even if a different algorithm is specified in the forecast engine settings.
  • The Crostons technique is used and the values for the SMP Chance of Event output parameters are updated. For other ATT techniques no value is returned for these output parameters.
  • A model is setup by the engine and processes the returned values based on the standard flow.
