PP - The Common Planning Strategy used

The planning strategies are maintained in Customizing for Demand Management in SM30 - V_T461S.

Define the Planned Requirement Type and assign the requirement class in OMP1.

Define the requirement class in OMPO.

Check the independent requirement and consumption of requirement class in OMPC.

Maintain the message for invalid requirement type in OMPJ.

You define the strategy group in SM30 - V_T461P.

You define the Plant to MRP group in SM30 - V_T438M_S.

Maintain the consumption mode and period of adjustment in SM30 - V_T438M_V.

Listed here are some common used planning strategies :-

Strategy 10 in summary :-

1. Sales Order creation - no impact.

2. Goods Receipt - reduce the planned independent requirement during MRP run
For e.g. if PIR is 100, quantity remained as 100 in PIR, however during MRP run,
100 will not be included in the MRP planned as stock is available.

3. Delivery - minus the quantity for the oldest planned independent in demand management.
For e.g. if PIR is 100 and delivery 90, PIR becomes 10 (withdrawal 90).


10 LSF Make-to-stock production KSL Sale from stock without independent
requirement reduction

Choose this strategy if you want production to be determined by a production plan (Demand Management) and if you do not want sales orders to influence production directly.

You must maintain the following master data for the finished product:

Strategy group 10 on the MRP screen.
Item category group (for example, NORM) on the Sales Organization screen.
Availability check field in Customizing so that you perform an availability check
without replenishment lead times (in the standard system, you must enter 02 here).

In net requirements planning according to strategy 10, the order does not create a requirement; the sales order is displayed, but does not generate planned orders.

The planned independent requirement is reduced during processing of the goods issue.
Old quantities can still be retrieved by using either
Goto -> Schedule line history in Demand Management, or by using the total requirements list
(Evaluations -> Display total requirements from the Demand Management menu).
The quantities issued are displayed in the Withdrawal quantity field.

The system always reduces the oldest planned independent requirements unless the consumption fields (Consumption mode, Fwd consumption per., Bwd consumption per.) are maintained in the material master or in the MRP group.


11 BSF Gross planned independent requirements KSL Sale from stock without independent
requirement reduction

Strategy 11 in summary :-

1. Sales Order creation - no impact.

2. Goods Receipt - minus the quantity for the oldest planned independent in demand management.
For e.g. if PIR is 100 and delivery 90, PIR becomes 10 (withdrawal 90).

3. Delivery - no impact as delivery is issue from sales order.

This strategy is particularly useful if you need to produce, regardless of whether you have stock or not. For instance, steel or cement producers might want to use this strategy because they cannot shut down production; a blast furnace or a cement factory must continue to produce, even if this means having to produce to stock.

You need to maintain the following master data for the finished product:

Maintain strategy group 11 on the MRP screen.
Set the Mixed MRP indicator to 2 on the MRP screen.
Maintain the item category group (for example, NORM) on the Sales Organization screen.
Maintain the Availability check field so that you perform an availability check without the replenishment lead time (checking group 02 in the standard system).
