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).

20 KE Individual sales
order without
consumption
Strategy 20 in summary :-
1. Sales Order creation is the only impact.
2. Demand management not in used.
In make-to-order production, a product is produced specifically for an
individual sales order. This planning strategy is used when planning of the
(parent) product is not required or not possible. Neither Demand Management is
involved in this process, nor is there an allocation mechanism. Orders are taken
as they come. This strategy represents a production procedure in which each
product is only produced once, although over time the same or similar production
processes are repeated. Each product is specifically produced for an individual
customer so that the finished product is rarely placed in stock.
You also must maintain the following master data settings for the finished
product:
Strategy group 20 on the MRP screen
Item category group (such as NORM) on the Sales Organization screen
40 VSF Planning with final assembly KSV Sales order with
consumption
Strategy 40 in summary :-
1. Stocks on hand reduces the PIR during MRP run.
e.g. if stock is 100 and PIR is 100, MRP run will not prompt 100 for
procurement.
if stock is 0 and PIR is 100, MRP run will prompt 100 for procurement.
2. Sales order creation reduces the PIR.
e.g. if PIR is 100, sales order 90, PIR becomes 10 (withdrawal 90).
3. Delivery reduces the Sales Order.
This strategy is probably the most widely used make-to-stock strategy. It makes
sense to use this planning strategy if you can forecast production quantities
for the final product.
Planned independent requirements are consumed by incoming sales orders so that
the master plan is always adjusted to suit the current requirements situation.
This means that the important feature of this planning strategy is that you can
react quickly to customers� requirements. The smoothing of the master plan is
less important.
You must maintain the following master data for the finished product in the
material master:
Strategy group 40 on the MRP screen.
Consumption parameters (Consumption mode, Bwd consumption, Fwd consumption) to
allow
consumption of independent requirements. If no consumption parameters are
maintained in the
material master, the system uses default values are taken from the MRP group.
To control consumption, you maintain a consumption mode as well as a consumption
period.
Item category group (for example, NORM) on the Sales Organization Data screen.
Four important points :-
1. Planned independent requirements are used to trigger the procurement and
production of
the necessary assemblies and components before receipt of the sales orders.
2. As soon as the sales order is received, it consumes the planned independent
requirements.
3. An ATP (available to promise) logic during sales order processing will
checks whether
sufficient planned independent requirements have been planned to cover the
sales order.
4. Requirements from the sales orders are passed on to production and can lead
to changes
made to procurement if the requirements from the sales orders exceed the
planned
independent requirement quantities. If there is insufficient coverage of
components
(the sales order quantities exceed the planned independent requirement
quantities), the
sales orders cannot be confirmed. The system therefore automatically adjusts
the master
plan. Planned independent requirement quantities that are left unconsumed
increase the
warehouse stock of the finished product.
