The system performs the sporadic test as part of automatic model selection . If the sporadic test is successful, the system selects all forecast strategies that you assigned to the sporadic test in Customizing.

Features

To decide whether the demand of a product is sporadic, the system checks whether the number of zero-demand periods exceeds a specific percentage of the total number of periods.

You can specify the total number of periods that the system considers for the sporadic test in the forecast profile on the Model Parameter tab page in the Initialization Periods for the Intermittent Forecast Model field. You can specify the number of zero-demand periods on the Model Selection tab page in the Zero Demand Periods in Intermittent Forecast Model field. The system uses these values to calculate the minimum percentage that the number of zero-demand periods must correspond to for the product to be considered as having sporadic demand.

If you have not specified a value in one or both of the Initialization Periods for the Intermittent Forecast Model or Zero Demand Periods in Intermittent Forecast Model fields, the system uses 66% as the percentage. In this case, at least 66 % of the total demand periods of a product must be zero-demand periods so that the sporadic test for this product is successful.
