hi
what special setting should i make to execute both aggregate and disaggregate planning in the system ,i have with me product group A and A1 and A2 all belong to the same group A should i create a charc. and key fig for A1 and A2 separately ? and after that how do i proceed ? should i run forecast for A1 and A2 separately ? got stuck at this point ,
can you please give some clarity on this aspect and how do i incorporate aggregation and disaggregation in the system? please throw some light on this issue.
thanks
