• Key Concepts: 
  Top-level demand is a term used in SAP's Predictive MRP (PP-PMR) component. It is the total demand for a material that is calculated from the sum of all lower-level demands. This includes both planned and unplanned demands, such as sales orders, production orders, and stock transfers. 
  
  How to use it: 
  Top-level demand is used to determine the total demand for a material in the PP-PMR component. This helps to ensure that the material is available when needed and that there are no shortages or overstocks. The top-level demand can be used to calculate the safety stock, which is the amount of material that should be kept in stock to meet customer demands. 
  
  Tips & Tricks: 
  When calculating top-level demand, it is important to consider both planned and unplanned demands. Unplanned demands can include customer orders, production orders, and stock transfers. It is also important to consider any seasonal fluctuations in demand when calculating top-level demand.
