I would like to execute forecast for a specific material.
Then I'm in MM02 in forecasting view, I filled all necessary parameters and I press "execute forecasts".
I received different pop ups, and one is "Between 11.2006 and 10.2011 all historical values are zero".
If I go out of this, and press on "Consumption vals", I have no data for unplanned consumption but if I click on "Total consumption", I got all values for each period of my historical periods.
So why do I have this message that historical values are zero? Then I have no chance to execute forecast with that behavior.
Same with several other materials.
Thanks for help.
In MM of forecasting view there is filed Hist. periods which you could have probably maintain more than 12 months say 60. So starting from current months it will go backward & search value for last 60 months. In your case it is not finding any past values. Have you maintain it in Additional data of material master Consumption tab ? Maintain some values for months & then try
Yes, I have one Consumption tab in Additional data of material master.
In there, there is no data for unplanned consumption, but there are values for total consumption (and same figures for corrected value) from January 2006 till Oct 2011.
Is it what you mentioned? If yes, why do you think this still does not work?
Thank you in advance,
