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)
Enterprise Planning can generate four types of planned orders:
- Planned production orders
- Planned purchase orders
- Planned distribution orders
- Planned Production Schedules
These are directly created:
- Production Schedules
- Purchase Schedules
- Subcontracting Schedules
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.
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.
LN shows the production plan and the purchase plan as planned production orders and planned purchase orders, with a blank Order Number field.

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.
Item order plan
The Item Order Plan (cprrp0520m000) session provides a graphical representation of the planning breakdown and projected inventory to help analyze critical data and highlight areas that require immediate corrective actions. You can also view the warning statistics to track exceptions, late supplies, unconfirmed plans, and pending transfers.
Use these charts and statistics to understand supply coverage, identify planning issues, and monitor projected inventory across sites:
- Planning Breakdown: This donut chart can be used to analyze the total supply coverage by combining stock on hand, planned inventory transactions, and planned inventory movements.
- Warnings: The statistics display the counts of key operational indicators, including the number of exception messages, late supplies, unconfirmed plans, and pending transfers
- Projected Inventory: This graph helps to monitor inventory trends, receipts, issues, and safety stock across sites.
