Is it possible to aggregate OKRs results automatically on parent OKR level, so you see immediately, the corresponding and more interesting result on top level? 

In that case 31.25% form B-Customers and 85% from A-Customers should be a bit more than 1.25% on the Enterprise Objective perspective. 

is there something i need to trigger there,  as the percentage is greyed out on the parent objective, so i assume there is an automatism embedded.

could you please help me on that one?

merci!
