Statistical Forecasting

[Krishna1]

Hello experts,

We are seeing an issue in our production system with state forecasting....

Issue is output KF is getting value of 0.0001 even though there is no value in Input KF for specific products. We expected system to assign ZERO or assign null value to output KF when there is no value in input KF...

FYI - We set global parameter FORECAST_ESCAPENULL equal to 0.

Please share if you have similar experience....

Thanks,

Krishna

Hello Krishna

As per the current system design: in case the History data is not available (i.e. NULL) or is <0.001, then system uses 0.001 as History data. That is why system is showing very small values as forecast data and not zero. This is designed so, to avoid calculations get divided by zero for certain forecast models like Seasonal Model.

In the next patch, the system design will be improved and the minimum historical data can be maintained with the Global parameter "HISTORY_MIN_VALUE" under the parameter group "FORECAST". If this parameter is not maintained, the default 0.001 will be used. Please note that this parameter has to be maintained as number in integer or decimal formats.

Hope this helps.

Thanks

Praveen,

Thanks for your quick response.

We are on 3.0.2.1...Are you talking about patch 3.0.2.2?... Do you know if  there is any OSS note or any other options is available to implement future fix in current release 3.0.2.1?...I couldn't find any note.

We use forecast output KF if denominator of the calculation which is causing numeric overflow issue.

any insights appreciated?

Thanks,

Krishna

Hi Krishna,

There is a note on this 2107574 - Forecast generates wrong or no result

This should also be available as part of 3.0.2.2. You should upgrade to this latest patch.
