Dear,

MRP - Material Requirements Planning

CBP - Consumption based planning,

Basically, there are two types of standard materials planning procedures in SAP, which are:

1. Traditional Material Requirements Planning (MRP)

In traditional Material Requirements Planning (MRP), sales order, planned independent requirements, reservations, dependent requirements that are created by BOM explosion, and so on are planned directly as requirements. The materials planning procedure will create procurement proposal only if these requirements will result in shortage of material stocks at a certain time. There are no other requirement that can trigger a procurement proposal. This procedure is used in u201CPD-MRPu201D MRP Type in standard SAP R/3.

MRP is especially useful for the planning of finished products and important assemblies and components (A materials).

2. Consumption Based Planning (CBP)

Consumption-based planning (CBP) is a materials planning procedure based on past consumption values that determine future requirements by using forecast or other statistical procedures.

Originally, in CBP, planned independent requirements or dependent requirement will not be considered in the net requirements calculation. Instead, it is triggered when stock levels fall below a predefined reorder point or by forecast requirements calculated using past consumption values. So, all the planned independent or dependent requirements in a certain period of time should have been considered before (when set the reorder point or calculate the requirement forecast).

Consumption-based planning procedures are simple materials planning procedures which we can use to achieve set targets with relatively little effort. Therefore, these planning procedures are used in areas without in-house production and/or in production plants for planning both B- and C-parts and operating supplies.

There are three procedures in Consumption Based Planning (CBP), which are:

a.Reorder point planning

In reorder point planning, SAP checks whether the available stocks are below the reorder point that has been set for the material. If they are, SAP will create procurement proposal.

We can determine the reorder point manually (u201CVB-Manual reorder point planningu201D MRP Type in standard SAP R/3) or, it can also be calculated automatically using the material forecast (u201CVM-Automatic reorder point planningu201D MRP Type in standard SAP R/3).

The reorder point should cover the average material requirement/consumption expected during the replenishment lead time (procurement processing time + planned delivery time + GR processing time). Besides the average consumption, we also should consider safety stock. The safety stock exists to cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays. Therefore, the safety stock is included in the reorder level.

The following values are important for defining the safety stock:

Past consumption values (historical data) or future requirements

Vendor/production delivery timelines

Service level to be achieved

Forecast error, that is, the deviation from the expected requirements

In standard SAP R/3 system, besides u201CVB u2013 Manual Reorder Pointu201D and u201CVM u2013 Automatic Reorder Pointu201D MRP Type, there are also other MRP Types that have reorder point as its basis to calculate requirement with additional procedure which count external requirement (sales order and manual reservation) as a requirement. The MRP Type are: u201CV1-Manual reorder point with external requirementsu201D and u201CV2-Automatic reorder point with external requirementsu201D.

b.Forecast-based planning

In forecast-based planning, historical data is used in the material forecast to estimate future requirements. These requirements are known as forecast requirements and are immediately available in planning.

The forecast, which calculates future requirements using historical data, is carried out at regular intervals. This offers the advantage that requirements, which are automatically determined, are continually adapted to suit current consumption needs.

This procedure is used in u201CVV-Forecast-based planningu201D MRP Type in standard SAP R/3.

c.Time-phased materials planning

In time-phased planning, historical data is also used in the material forecast to estimate future requirements. However, in this procedure, the planning run is only carried out according to predefined intervals. If a vendor always delivers a material on a particular day of the week, it makes sense to plan this material according to the same cycle, in which it is delivered.

This procedure is used in u201CR1-Time-phased planningu201D MRP Type in standard SAP R/3.

Besides all procedures that have been explained above, in SAP R/3 system we can create other procedures according to our own needs. We can do it through configuration with SPRO T-code.

Hi,

Material requirements planning asself clear from the name is requirements for all the materials that have to be considered for planning.

The MRP comprises of MRP, Consumption based planning, Time phased planning etc. CBP and Time phased planning are all the types of MR planning.

The consumption based planning may be forecast based planning or thr Re-order type planning wherein the past consumption values of the materials are taken in to consideration for the future forecaast of the materials.

Re-order point contains the re-order point when the stock falls below the re-order point the system automatically proposes Purchase requisitions for the same and thereby the material has to be procured.

Hope this helps.

CBP is a part of MRP

Hi,

Mateiral req. planning is of 2 types

1. MRP type

2. COnsumption based planning

In second one you use the Consumption values for the further planning....you enter the consumption values in the MMR....

Consumption-based planning procedures are simple materials planning procedures, which you can use to achieve, set targets with relatively little effort. Therefore, these planning procedures are used in areas without in-house production and/or in production plants for planning both B- and C-parts and operating supplies.

The prerequisites for implementing consumption-based planning are:

If you use forecast requirements, the consumption pattern should be fairly constant or linear with few irregularities.

Your Inventory Management must function well and should always be up-to-date.

You use the link for more abt CBP:

hope it helps...

Anything else revert back...
