Seasonal forecast calculation details
Hi,
I'm using transaction MM02 to calculate seasonal forecast ("S" model", with no optimization marked);
I entered 18 months consumption and get a correct forecast for the next 18 months.
Thanks to the formula described in HELP.SAP, I tried to reproduce the calculations in excel, but unsuccessfully. The main question is : what is "V(t)", actually.
Can someone send me the correct formula for G(t), and tell me what "V(t)" is ?
Monthly consumptions, calculated forecast and used parameters are in the attached file.
Thanks a lot in advance,
Sandrine
