Forecast model K (Constant with smoothing factor adjustment)

Hi All,

i am using forecast model K in materail master. I would like to know the system calculation on forecast value?

For Example:

Consumption qty maintained in material master for last 3 months.

Period Total consumption

04.2011 100

03.2011 150

02.2011 200

When i am using Forecast model K, system is calculating as follows,

Period Orig. HV Corr. HV Ex-post FV Orig. FV

M 02.2011 200 200

M 03.2011 150 150 200

M 04.2011 100 100 155

M 05.2011 106

05.2011 Forecast value is 106, Basic value is 105.500, Error total is -105 and MAD is 27.

I would like to know the system calculation of these value. Particularly Basic value and MAD.

And also the difference between Forcast Model D and K if possible.

When i am using Forecast model D, system is calculating as follows,

Period Orig. HV Corr. HV Ex-post FV Orig. FV

M 02.2011 200 200

M 03.2011 150 150 200

M 04.2011 100 100 190

M 05.2011 172

Basic value 172.000, MAD 38, Error total -140

Thanks in advance,

Babu
