I am listining to one of the Oracle recorded webinar on Forecast consumption in supply chain plan under planning central cloud. I do see option that external forecast can be consumed at various level such as customer, customer site, demand class and item level.  However Oracle customer connect video very categorically mentioned that external forecast can only be consumed at item level.

It is possible that enhancement may be made to include additional level of consumption or it is also possible that these options are there but they will not work.  The only option which will work is item.
