Define Performance Settings
In this step you can optimize performance, as the determination of characteristics and key figures can be very performance intensive.
You can switch off communication structures in Performance Customizing.
At operation level, you can activate or deactivate some key figures and key figure groups. This affects the work center analysis, in which, for example, the process of determining capacity key figures at the time of evaluation is complicated.
You can set the units for some key figures. These key figures are then converted to the units selected as soon as is possible. This makes it easier to make a comparison, as unit conversion is not possible in the standard analyses.
It is also possible to display co-products as items and to read the work centers for the relevant costs. The latter is particularly performance intensive.
With effect from Release 4.5A, there are new run schedule header information structures for goods issues (S226) and costs (S227). They enable you to have the previous information structures S026 and S027 updated only by process and production orders. They can, as previously, also be updated by run schedule headers.
See the appropriate 
Release Note for more information.
