Carrying out Capacity Planning (MPS/MRP) 
You can carry out capacity planning in three different ways, depending on the function called up:
- From within planning as capacity leveling
- From the evaluation "current stock/requirements list" as the capacity situation
- From within planned order processing as the capacity check
Capacity leveling makes it possible to check individual work centers for overloads and if necessary to dispatch planned orders at other times or with other quantities.
The capacity situation also provides an overview of available capacity and the load for the individual work centers, but you cannot dispatch planned orders differently from within the capacity situation.
The capacity check from within planned order processing checks whether overloads may occur for the work center(s) selected, which might endanger production of the planned order. It is only if there are overloads that the system branches to capacity leveling to make changes there. Leveling in planned order processing is only possible when creating or changing an order. When displaying the planned order the system branches to the capacity situation.
In the capacity planning table you can dispatch the capacity requirements for detailed planning continuously through time and for specific operations.
