Annual Projected Demand IN "Planning Detail Report (MRRDPR) "

HI

   i  feel unsure about the formula of  Annual Projected Demand in Planning Detail Report  when i read the white paper

Balancing Demand & Supply: A Brief Guide to MRP logic: An Oracle White Paper Feb 2003(文档 ID 230439.1)

  In the paper,

Annual Projected Demand =(Demand for Planning Horizon) * (365/length of Planning Horizon)= 125 * (365/183) = 249 (rounded).

        Length of planning horizon = Plan Horizon date - Anchor Date = 12-Aug-2003 - 10-Feb-2003 = 183 days. "Plan Horizon date " and "Anchor Date" is the parameters of "Planning Detail Report".

And i make a test in my test env 11i(11.5.10.2).Plan Horizon date=08-09-2018,Anchor Date=08-06-2018,Annual Projected Demand =480,
