ByD System Configuration - All Demand Consumes Forecast

Hi there, I need to do system configuration for Supply Planning and Control, activity: All Demand Consumes Forecast. I am not sure how to do it. I understand the 3 concepts of the Demand Management Procedures: 1. All demand consumes current forecasts 2. All demand consumes preceding forecasts 3. All demand consumes adjacent forecasts. I am unsure what to fill in the field Maximum consumption in selected timeframe (%). Also, do I copy the Procedures and add a Z next to it?
