Net requirements planning. That is even the warehouse/storage location
stock is also taken into account besides planned receipts / issues during
planning for calculating the order quantity. Planned Independence Requirement
quantity is reduced at the time of Goods Issue for delivery.
Strategy 11 - PIR
Type - BSF
Gross requirement planning. Warehouse / storage location stock is not considered,
and only planned receipts / issues are considered. Also Planned Independent
Required quantity is reduced during Goods Receips for production / planned
order (Repetitive). It is generally recommended for mass production
industries and process oriented industries where the production has to
be carried on, regardless of the stock available. The constraint in such
industries is that it is not economically viable / possible to stop production.
Strategy 30 - PIR
Type LSF - Production only with sales order (Demand Management
entry are ignored during MRP run)
Maintain the following master data for the finished product:
Strategy group 30 on the MRP screen
Availability check field (on the MRP screen and the Sales: General/Plant
screen) so that you can perform an availability check with replenishment
lead times (01 in the standard system)
Item category group (for example, NORM) on the Sales Organization screen
Strategy 40 - PIR
Type VSF -
to Order Production - Production triggered by sales order. (Widely
use around the world.)
Planned Independent Requirements will be reduced by sales order delivery
to reflect the current stock requirement. (depending on your configuration,
sales order will consume the VSF (planned independent requirement) quantity
on the same date or two to three days away from it)
You can set up the consumption parameters in the material master on the
Check whether the fields Consumption mode, Bwd consumption, Fwd consumption
contain entries. If empty, default values are taken from the MRP group
parameters in Customizing. If these fields are filled in the material master,
they override the MRP group parameters.
In MD04, VSF will disappear once it is consume by the sales order
Choose Logistics -> Production -> Master Planning -> Demand Management
-> Evaluations -> Display total requirements. (The Total Requirements List
shows only those sales orders that have reduced the independent requirements.)
Strategy 52 - PIR
Type - VSE
The lot size key EX must be set in the MRP screen because lot size optimization
would be incompatible with the allocation logic, which could result in
over-planning and incorrect result in the ATP check.
You also must ensure that no rounding profile or rounding values are taken
Maintain consumption parameters (Consumption mode, Bwd consumption, Fwd
consumption) so that the independent requirements can be found. For more
information, see Consumption Strategies and Logic.
Maintain the item category group (for example, NORM) on the Sales Organization
A BOM is required for the finished product. There are no major implications
for the BOM components. However, it is important to note the following:
You need to set the MRP type to P* (or M*) on the MRP screen to plan the
components in MRP.
You may want to consider setting the Individual/coll. Indicator to 2 on
the MRP screen as a starting point for your master data setup.
Strategy 63 - PIR
Type - VSEV
Set Ind./Coll. Indicator to 2 in MRP4 View for all your lower level
components. It allows you to build or purchase some components only after
receipt of the sales order.
