We need to allocate $100 from Selling, Distribution etc. (Lvl 0 members of Function dim) into Product-Channel combination, say in 40% and 60% for Jan.
The users input these percentages in data forms, which can vary for each month.
The $100 is in Selling-> Geography (it is another dim), which needs to be allocated to Prod-Channel combination.
My percentages in data form are in Prod-Channel-Geography.
