Split Valuation

Hi,

Based on documentation regarding Split Valuation, we could differentiate the costs of a material based several categories. For example, we could have different cost for in-house and externally procured materials. My questions:

1. What is the price control for a material with split valuation assuming that I want to differentiate between in-house and externally procured?

2. If I use split valuation for raw material component, how does product cost controlling know which value type to choose when I cost the higher level material (using cost estimate with quantity structure)

3. We have Material Ledger/Actual Costing activated, does anyone know if split valuation works with ML/AC?

Thanks for your reply.
