BIAS Forecast Error CV calculation

[#1]

Hello,

I have some questions about the settings in the forecat error cv tile.

At the end of this tile there are settings, which I don't understand what are the consequnce of this settings.

Of cource I have see the help side https://help.sap.com/viewer/c93e84a3d93f4623bda2dd70b2dd66ca/1902/de-DE/b68322f4b3004451a155386bd7cb... but this was not so helpful.

Follow settings are unclear for me:

1.) Adjust Bias of Forecast.

What mean this? the BIAS is calculated base of the forecast. What happened if I adjust the BIAS of the forecast

2) Bias Adjustment Method

Here is the same question as before. What happend, if I used the positive BAIS method for example

3) Bias Confidence Interval

Thanks in advance

Regards

Oliver

Hi Lingaiah,

thanks fpr the response.

That sounds for me, that with the checkbox "Adjust bias of forecast", I can at the next step say, which BIAS I want to adjust -> positvie, negativ or both.

But how are the system adjust then the BIAS ? what are the algorithme and the logic of this ?

Thanks in advance

Hi,

Bias forecast error CV calculation is applicable for the inventory optimization process. During forecast error CV calculation system considers the sales history or historical values and forecast to adjust the bais.

The methods Adjust Bias of Forecast, Bias Adjustment Method, Bias Confidence Interval used to control the forecast error calculation with manual inputs, you can define these bias calculation to output key figures.
