Forecasting strategy 35 (Season + Linear Regr)

[Former Member]

From Interactive Demand Planning, we open up a Planning Book / Data View, picked a selection profile and loaded the history data.  We have at least 2 years of history data in weekly buckets.  We click the Univariate Forecasting button to open up the Forecasting screen.  On the model tab, we choose Season + Linear Regr.  On the parameters tab, we set "Periods per season" to be 52. 

Then we click Forecast Run.  APO successfully completed forecasting but the Periods per season got reset to 1.  Every single time.

Does this happens to any one before?

This is not a standard functionality.  SAP Global Support helped to identify a BAdi /SAPAPO/SDP_FCST5 that was implemented in the system (we lost documentation).

By removing the BAdi, we were able to see the standard functionality again.
