- A capacity availability check is not performed with Material Requirements Planning (MRP).
- Capacity Planning must be executed separately in a second step.
- Master data, planned orders, and production orders provide data that can be used to represent available capacities and capacity requirements.
- The available capacity is a measure of the work that a capacity can perform per workday.
- The capacity requirement is a measure of the work required by the individual orders at a capacity at a certain point in time.
- Capacity requirements are created when the planned orders or production orders are created.
- In Capacity evaluations, these requirements can be compared with the available capacities.
- In Capacity leveling, capacity shortfalls and overloads can be leveled. You can use alternative suitable resources or the sort criteria to plan optimal loading.
- The available capacity represents the capacity available for production at a work center or resource.
- You can schedule the sequence of operations to determine the times for the capacity requirements.
- To calculate the capacity requirements, the system uses formulas containing the dates and quantities for production requirements.
- Capacity evaluation gives you an overview of the load and the production requirements.
- Capacity leveling allows you to achieve optimal planning and an optimal load.
- Capacity reduction occurs when operations are confirmed or order quantities are reduced or canceled.
- The available capacity is the work that can be done by a capacity at a work center per working day.
- You can store the operating time and the daily available capacity at a work center in a capacity in the work center.
- You identify a capacity at the work center using the capacity category.
- Various capacity categories can be assigned to the work center, for example, a machine capacity or a labor capacity, but each capacity category can only be assigned once.
- The available capacity is determined by:
- Work start and work finish times
- Length of breaks
- Rate of capacity utilization
- Number of individual capacities which the capacity consists of
- In capacity evaluations, the capacity requirements are compared with the available capacity.
- Capacity evaluation involves:
- Determining the available capacity
- Determining the capacity requirement
- Comparing the available capacity with the capacity requirement
- The standard overview periodically compares the available capacity with the capacity requirements for the selected work centers for each capacity category.
- The loads and remaining available capacity are also listed.
- In capacity leveling, capacity shortfalls and overloads can be leveled.
- You can use alternative suitable resources for processing or the sort criteria to plan optimal loading.
- The main function of capacity leveling is to dispatch operations.
- Operations are dispatched to fix them at a point in time when there is sufficient capacity for them to be carried out.
- The objectives of capacity leveling include:
- Leveling overloads and underloads at work centers
- Achieving optimum commitment of machines and production lines
- Selection of appropriate resources
