Hi Prasanna,

1) While maintaining the univariate forecast profile in DP, these (alpha, beta) values will be maintained. The relevance of these settings will be available under the link

2) Typical DP issues that comes during support ticket resolution will be non-availability of data in planning book, Master data maintenance (CVC, planning book objects, MPOS etc.,), DP related consistency checks, Data extraction, etc., For most of the issues, I would recommend to go through sap help website and also SAP SDN previous answers. If still not answerable, please post a query in SAP SDN. If still not, SAP OSS message can be raised.

Prasanna,

Exponential Smoothing Models use alpha/beta/gamma values and are one of the most popular models among practitioners.

In a Triple Exponential Smoothing Model

alpha - Must be a value in the range 0.0-1.0. Values above 0.5 are uncommon

beta - the second smoothing constant, is used to smooth the trend factor in the time series. Must be a value in the range 0.0-1.0. Values above 0.5 are uncommon

gamma - the third smoothing constant, is used to smooth the seasonality in the time series. Must be a value in the range 0.0-1.0.

Details of how you can use these values are on help.sap.com

You can search for more info on the internet.

Hope this helps.
