Hi Anurag,
Thanks for your input. I have gone thru the information earlier itself which
you have provided. The values are wrong which SAP is giving if i compare
with the formulas which you have provided.
Do not know why. just to know is there have any some other formula for
seasonal model? i double checked SAP values are not matching with the fomulas
for seasonal model.
Hello Sumanth,
Sorry for inconvenience.
What I can tell you from this SDN document is that you can understand the calculation of forecast using various parameters.
About the formulas , good that you noticed that the some of values are not visible ( in the blank spaces) might be it would have been deleted by some mistake while uploading to SDN by the writer)
So what I would suggest you that you can use formulas given in sap help link which you have i.e.
http://help.sap.com/saphelp_apo/helpdata/en/ac/216b83337b11d398290000e8a49608/content.htm
Please share you views,
Thanks,
Anurag
