SAP IBP error measures

[OliverA41]

Hello,

the link on the SAP help page shows when the corresponding error measure is useful.

Fehlermaße | SAP Help Portal

One advantage of IBP is that it can automatically determine the best forecast. to do this, I build a profile with various forecast algorithms and have the best algorithm selected according to an error measure.

But how can I understand the note on the SAP page? I have planning objects that have a forecast erorr for optimising the forecast for average demand (i.e. MAPE , MPE) and other seasonality and therefore need MASE or MAP.

I can only select the best forecast model according to an error measure, which may then have been calculated with a "not so suitable" error measure.

Hi Oliver,

the help page is meant to help you understand how the different error measures works. Of course there is no "one size fit all" when it comes to algorithms and error measures.
If you feel that separating planning objects with seasonality from planning objects without seasonality is important in terms of error measures, then I suggest you forecast these separately (using the Time Series Analysis and a corresponding planning filter) with two different forecast models. So you can use different best fit models for the seasonal planning objects and for the not seasonal ones.

Best regards

Laura

Hello Laura,

thanks for the response. This is the information, which I missing. The result of the time series analyze are stored in attributs, aren't it ? And than I can use different planning filter which work with different forecast profiles .

Hi Oliver,

yes you can store the result of the time series analysis in attributes and use it for the planning filter. Here you can find some more information: https://help.sap.com/docs/SAP_INTEGRATED_BUSINESS_PLANNING/feae3cea3cc549aaa9d9de7d363a83e6/0827673a...
