Changing the Operative Rate/Takt Time 
Use
You use this function if you want to override the planned rate for a short period of time. With the operative rate you can react to any short term changes in requirements or supply. For example, you can enter an operative production rate for a shift.
Integration
You can enter or change the operative rate in Line design , in Sequencing and in the planning table .
Prerequisites
You must have created a line hierarchy in the system.
Features
The operative rate controls the time that elapses between a material entering and leaving the production line, for the period entered. Therefore, the operative rate overrides the planned rate, as far as supplying material to the production line is concerned. The system still uses the minimum takt time to determine the time that a material spends in a takt.
