Given a simplistic forecast of 100 units per period for 12 periods, zero existing demand, I am trying to confirm the difference between using reduction principle transactions-reduction key and transactions-dynamic period. My understanding is that if a sales order for 150 units were to be booked for period 2, under reduction key it would fully consume the period 2 forecast but not affect any other period. Under dynamic period it would fully consume the period 2 forecast and also partially consume the period 3 forecast. When I execute this scenario, though, I get identical results under each method–period 2 fully consumed, zero impact on period 3.
Can anyone explain the purpose and use of dynamic period compared to reduction key? Have you seen it actually work?
