Executing MRP for Long-term Planning 
Use
The following functions are available for executing the planning run which is always carried out with reference to a planning scenario:
- Total planning
- Single-item, single-level planning
- Single-item, multi-level planning
- Single-item, multi-level planning in simulative mode
- Make-to-order planning
- Individual project planning
Prerequisites
You must have released the planning scenario.
Features
- You can carry out long-term planning as either net requirements planning or as gross requirements planning.
- MRP for long-term planning is carried out at plant level. The storage locations which are either excluded from the planning run or which are planned separately are also planned in the plant segment.
- Only planned orders are created in the planning run in long-term planning. Therefore, in the initial screen for the planning run, you cannot set a creation indicator for purchase requisitions or delivery schedules.
These simulative planned orders are created with different order types, depending on whether the materials are procured internally or externally. - The system plans all low-level codes of the planning file created for the planning scenario.
- The planning horizon is not relevant to long-term planning which means that only the two planning run types, net change planning and regenerative planning are available.
- You can carry out MRP for long-term planning with a separate BOM. That is, with a BOM specifically for long-term planning.
Actions
After starting the planning run, the system carries out MRP for the specified planning scenario and displays the following results:
- At finished product level, the system creates simulative planned orders for the long-term planning version of the demand program.
- Simulative dependent requirements and simulative planned orders are created for the components.
- If you set the indicator "2" in the initial screen of the planning run in the Scheduling field, the system creates simulative capacity requirements for the materials produced in-house.
