History gets changed after running univariate forecasting

Hi Experts,

When I run Univariate Forecasting,the actual history value gets changed for full past horizon.This is the same actual history which is used in the forecast profile.

Suppose Actual History is 186 in Week 28,after forecasting - the actual history becomes 378 for week 28.This happens with all the buckets in the past. Due to this change in history - forecasting also gets affected.

It is taking fix value from CT_VALUE_TAB table no matters what is the actual history.

Not sure how this table gets updated.

I deleted the whole history still after running the forecast interactively- we get the same new history values.

Please suggest.

P.S. - We are not using any corrected history concept.The same history time series key figure is used to forecast which is used in the forecast profile.

Regards,

Prabhat

Hi Prabhat,

After running Univariate Forecasting, History is getting doubled. So my assumption is that Forecast is calculated and getting saved on the History Keyfigure.

Which is the Keyfigure for saving your calculated Forecast? Is there any effect on them after running Univariate Forecasting?

Please check your Forecast Horizon(should be the positive number) and Forecast Keyfigure(shouldn't be the History Keyfigure) within the Master Forecast Profile. I guess there is an issue with them. In case if Master Forecast Profile dont have any issues, we need to back track the configurations related to forecast.
