PPC Rough-cut Dispatcher
Rough-cut planning is a levelling between capacity requirements and available capacity that occurs within predefined periods (e.g. month, week). The planning usually has a long-term focus, where MRP receipts can be created or adapted as required in the respective periods (“buckets”). At the same time, the capacities of ERP work centres are synchronised and periodic constraints are taken into account (e.g. maximum amount per day). Costs for production plans can also be calculated and optimised.
The PPC Rough-cut Dispatcher is a module fully integrated in SAP ERP and based on standard objects and functionalities. All major data for planning from the SAP ERP (e.g. planned and production orders) are invoked from the PPC Rough-cut Dispatcher – without any interfaces. Planning is both manually (e.g. by drag and drop) and automatically (using planning algorithms) possible and a multi-level analysis ensures planning transparency in all cases.
- Periodic capacity overview (period is defined by user)
- Real-time information about capacity workload in the plant
- Real-time information on the feasibility of customer inquiries on yearly, monthly, weekly, daily and shift level
- Central access to all major SAP ERP standard objects and capacity data
- No interfaces
- Flexible module that is quickly established
- Review and consideration of restrictions: supplier delivery capacity, storage capacity, supply shortages, etc.
Use of a basis period, for example a day or a shift, depends on the customer requirements. The periodicity is selected corresponding to the business case, for instance:
- During the strategic planning of the next financial year the buyer can gain an overview about required quantities of production resources. Required raw materials, machines and production tools are calculated based on the predicted demand volume of products. In this case a coarser granularity is to be chosen.
- During operative planning, orders are prepared and daily or weekly programs are forwarded to the production controller or shop floor foreman, who plans manually based on their experience. A finer granularity is better suited in this case.
The focus of rough-cut planning is not on the creation of a detailed sequence of planned orders. However, it can be an efficient and comprehensive preparation for the subsequent more detailed planning step.
The periodic planning ("bucket planning") covers several aspects of planning:
Capacity bucket planning: Jumping to the respective bucket shows the causes for overloads.
The result is an overview of orders with all required data. Dispatched orders are highlighted (blue)
as well as undispatched order (red).
