APO DP - fcst strategy 56 with user defined fcst error

[Former Member]

I am using APO DP V5.

I am using fcst strategy 56 in combination with a user specific forecast error defined by BADI /SAPAPO/SDP-FCSTERR.

The system is not choosing the fcst model with least error (for constant model) - rather it seems to be choosing the model with the 'initial value' of alpha specfied in the fcst profile.

Has anyone had problems in this area?

Thanks, Bob Austin

Hi Bob.

Not the answer, but maybe a clue.

Check the entries in the table /SAPAPO/FCST_56 using SE16 after running the forecast interactively to see the alpha optimisation error values. User Exit values should be included.

Hope this helps, Mark.
