What time element of midpoint scheduled operations can be reduced by reduction strategy settings while...

In SAP S/4HANA,midpoint scheduling(used in capacity planning, e.g., CM21, or PP/DS) schedules operations around a fixed midpoint (e.g., a critical operation), adjusting other operations forward or backward. Thereduction strategy(configured in Customizing, transaction OPU3, or work center CR02, Scheduling tab) reduces certain interoperation times to compress the schedule when dispatching:

Queue time(A): Defined in the routing (CA01, Interoperation Times tab, field: Queue Time), this is the buffer time before an operation starts. The reduction strategy (e.g., Level 1 to 6 in OPU3) can reduce queue time progressively (e.g., by percentage or to a minimum), allowing tighter scheduling.

Move time(C): Also in the routing (Interoperation Times tab, field: Move Time), this is the transport time between work centers. The reduction strategy can shorten move time to fit operations within capacity constraints, optimizing the overall schedule.

Teardown time(B) (routing, Standard Values, e.g., Teardown Time) is part of the operation’s base duration, not an interoperation time, so it’s not reduced by the strategy—it’s fixed unless manually adjusted.Setup time(D) (Standard Values) is similarly operation-specific and not typically reduced by interoperation-focused strategies. This is per SAP’s scheduling and reduction logic.
