Move Time 
You can maintain the move time
in the individual operations
in Customizing per location group in the move time matrix
In the interoperation times section of the Operation Details screen, you can maintain a minimum and a standard move time. If reduction measures are carried out, the system schedules the operations using the minimum move time (see also Reduction Measures ).
Only if you do not maintain move times in the interoperation times section of the Operation Details screen, the system determines the move time using the move time matrix.
