Basic value, seasonal index and trend calculation

[Former Member]

Hi,

We are using 2 forecast profile with model 30 (seasonal trend), and are trying to optimize the alpha & gamma parameters.

We've been reproducing the forecast logic based on these documents :

• Model Initialization
• Trend/Seasonal Models w. 1st Order Exp. Smoothing

Most of the time we get the forecast right, but we still have some discrepancies between estimated forecast (from "custom-made" model) and APO forecast. The discrepancy doesn't exceed 1%, but it still induce a bias in the parameters optimization.

We'd like to get the basic value, trend & seasonal index for a certain model/forecast profile to verify our calculations. Is there a transaction/table we can use to get these values ?

Thanks in advance,

Ben.

Note : I've seen a few posts with the following transaction, allowing the user to display the trend/basic value/seasonal index values, but I don't know this transaction, could you help ?

Hello,

This is screen of planning book, /SAPAPO/SDP94 after execution of forecast. And values coming from forecast profile defined Planning Area in /SAPAPO/MC96B - Maintain Forecast Profiles transaction.

All profiles contained in Tables /SAPAPO/DP440G Master Forecast Profile and /SAPAPO/DP440P univariate profiles.

Assign the forecast profile in interactive planning (/n/sapapo/sdp94) and execute the univariate forecasting (CRT+F8)

Best Regards,
