Order planning, an overview

Order planning is a planning concept that has the following aspects:

  • A method for maintaining planning data (in various degrees of detail)
  • A method for supply planning (by generating planned orders)

Order planning works with the following types of order plans:

The item order plan is based on detailed planning data from various sources. The item order plan is not stored as such, but is composed online when you run the Item Order Plan (cprrp0520m000) session. You can choose between various levels of detail for the item order plan, ranging from 28-day periods to the level of individual orders.

If multisite is activated, planning is done by planning cluster.

Order-based supply planning

During an order simulation (RRP run), supply is planned in the form of planned orders. You can carry out an order simulation in the following sessions:

  • Generate Order Planning (cprrp1210m000)
  • Generate Order Planning (Item) (cprrp1220m000)

For planned production orders, Enterprise Planning uses:

  • BOMs linked to the item and site combination to explode material requirements
  • Routings linked to the item and site to calculate lead times and determine the necessary resource capacity

Instead of using routings, Enterprise Planning can also use fixed lead times for planned production orders.

Note

Most horizons and time fences in Enterprise Planning are rounded to the end of a plan period. Therefore, you need to define plan periods for the scenario involved, even if you only use order-based supply planning.

The horizon of the Item Order Plan (cprrp0520m000) session is the planning horizon, so that you can check all the item's transactions time-phased. If an item does not have an item master plan, the planning horizon is equal to the order horizon. If you use the Convert Master Plan to Planned Orders (cprmp2240m000) session in combination with workload control, you must extend the item order plan view with the planning horizon.

  • Planned supply orders

    In the Planned Orders (cprrp1100m000) session you can:

    • Review existing planned orders
    • Modify existing planned orders
    • Manually create planned orders
    • Transfer to execution level

      You can transfer planned orders to the execution level in the Transfer Order Planning (cppat1210m000) session, or transfer an order manually in the Transfer Planned Production Orders (cppat1211m000), which you can access via the appropriate menu of the Planned Orders (cprrp1100m000) session.
