Dear Experts,
I thought I understood this well but I am at loss of reasoning
My historical data (history key figure) comes from another system and I don't know the data sources. May be its sales invoice quantity that I presume are always +ve !
In DP, this History key figure is used as-it-is (in the forecast profile and planning area) to generate a forecast
What should be the motivation to set / not to set "Zero Allowed" for the history key figure ?
Thanks
BORAT
