Hello,

I am facing a challenge in enabling a new forecast type - Opportunity By Quantity. 

When I go to Forecast settings, I click on 'Add forecast type', but then the only option I can select for Forecast Type is 'Product Families' (see screenshot attached). 

I do notice the following note: 'Select a forecast type you want to enable for users. Depending on your organization’s configurations, some forecast types will be available and others will not. '

How can I make the type Opportunity Quantity available for my organization?
