Consumption based planning

Question

Hi,
I need to configure the CBP based on Past consuption data of 3 months and also it should give me future forecast values for 3 months. also I want to use safety stock and Reorder level.
Which MRP type should be used and what are configuration setting required for the same.
Also pl.guide me on What will happen if there is sedden rise in the requirement is any month?
Thx

Hi,
MRP supports and helps the MRP controller in the task areas. These tasks include
determining type, quantity and time of the requirement, and scheduling corresponding
procurement elements. The automatic planning run for MRP determines shortage situations and generates the corresponding procurement elements. Possible
procurement elements of MRP are planned orders, purchase requisitions and
scheduling agreement schedule lines. The planned order and purchase requisition are
internal planning elements that can be changed, rescheduled or deleted at almost
any time.
In in-house production, the system creates planned orders for planning production
quantities. When planning has finished, the system converts the planned orders into
production orders. The system then converts the dependent requirements in the
planned order into reservations in the production order.
In external procurement, the system either creates a planned order or a purchase
requisition for direct planning of external procurement quantities. Whether purchase
requisitions are created for direct planning, or planned orders are created first, you
can use the creation indicator for purchase requisitions/MRP groups in the material
master record on the initial screen of the planning run. When planning has finished,
the planned order must be converted to a purchase requisition, which is subsequently
converted to a purchase order. The advantage of creating a planned order first is
the additional procurement proposal check that is executed by the MRP controllers.
Purchasing can only order the material when the MRP controller has checked the
planned order and converted it into a purchase requisition. Otherwise, the procurement proposal is immediately available for Purchasing.
Planning Levels of Consumption-Based Planning
Requirements planning takes place at plant level. In other words, the entire stock that
exists in the plant is considered in planning. However, the stocks of individual storage
locations can be excluded from MRP or planned independently. These stocks are then
not included in MRP at plant level. You can also execute requirements planning
for individual MRP areas. You can define the MRP areas yourself. This means
that several storage locations can be grouped together for one MRP area and that
requirements planning can be executed separately from the plant for these MRP areas.
MRP areas enable a differentiation of material requirements planning within a plant.
(MRP areas include the function of storage locations that are planned separately for
materials requirements.)
Planning Levels for Materials Planning is either
1. The Plant with Storage locations planned separately.
2. MRP areas
Basically, MRP areas are optional. You can plan all material requirements without referring to MRP areas.
There are three different types of MRP areas:
1. Plant MRP areas (obligatory) that are automatically created by activating
planning with MRP areas. Their numbers match the number of the plant. If no
more MRP areas are defined, the plant MRP area covers the entire plant.
2. Storage location MRP areas that are defined by the storage locations assigned
to them.
3. Subcontractor MRP areas that provide planning of the requirement of the
material provided for a subcontractor and are defined by the assignment of
this subcontractor.
Prerequisites for Consumption-Based Planning
The following prerequisites must have been fulfilled in order to carry out requirements
planning for a plant:
Requirements planning for the corresponding plant must be activated in
Customizing for Materials Management under Consumption-Based Planning u2192
Planning u2192 Activate Material Requirements Planning.
T-code - OMDU
The plant parameters for the corresponding plant must be activated in
Customizing for Materials Management under Consumption-Based Planning u2192
Plant Parametersu2192 Carry Out Overall Maintenance of Plant Parameters.
T-code - OMI8
In the material master record, you have to maintain the MRP data of the materials
that are subject to automatic planning.
I hope this may help u !
