Supply Preference Rules, a sub-set of Business Preference Rules, define which products, or Product Aggregates, receive, or are entitled to receive, a specific quantity of capacity in a specific time frame.

They are used to:

control mix of builds (e.g. Sole Source, key, margin or

commodity products)

reserve for specific Demand Classes (e.g. customer JIT

inventory)

build products in excess of Demand to load factories

They also include other characteristics that control inventory or

capacity usage (e.g. Batching / Rounding, lots on hold, small

lot partial usage)
