New requriment types for SNP optimization

Hi colleagues,

A standard SNP mantains planning with only 3 types of requirement: customer demand, corrected demand forecast and demand forecast. I can define 3 key figures to say to SNP optimizer “who is who” using standard KF functions 1001, 1002 and 1003.

But I need to define for one product-location 6 different types of forecasts with different ND costs. 

Questions:

1. Is it possible to add requirement types to use it in SNP1 tab of a product master?
2. Is it possible to create a customer key figure function to map a customer key figure with a new requirement type?
3. Is it possible to force an optimizer to take into account new requirement types as new demand classes?
