hi,

MRP : MAterial requirement planning...

Prerequisites:

1. Maintain MMR from MM01 for MRP views..

2. maintain the source list for the mateiral req. to be planned

3. maintain MD03 - single item single level planning

The main function of material requirements planning is to guarantee material availability, that is, it is used to procure or produce the requirement quantities on time both for internal purposes and for sales and distribution. This process involves the monitoring of stocks and, in particular, the automatic creation of procurement proposals for purchasing and production.

USE :

MRP tries to maintain the balance stock in the warehouse for the constant levels...

ADVANTAGE :

1. As the material level is seen constantly by the system, so you don't make any documents for the req. generated in the dept...so procurements is hit automatically as soon as the reorder point is touched..

2. No mistakes in the generated of the documents, so you avoid the entry errors...

3. Ontime processing of the requirements..

4. If req. the system also considers the availability check for the future req.

5. Auto PO can also be generated if done all the necessary settings..

Hi,

Lot size:

Key that determines which lot-sizing procedure the system uses within materials planning to calculate the quantity to be procured or produced.

Lot-size key field defines the lot sizing procedure.The procedure calculates the reorder qty in the planing run.The lot size can be defined for short term & long term periods.

The lot size calucltion can be configured in tcode:OM14 or

IMG-production-MRP-Planning-Lot size calculation-check lot sizing procedure.

When I create the PR through MRP run it automatically goes to PURCHASE REQUISITION TYPE (NB).

I want to make it in type PR03 ie. MATERIAL/SERVICE PR.

What customizing settings should be done for this?

Thanks & regards,

MRP run For multiple items

hi

it is Material Requirements Planning

Material Requirements Planning (MRP) enables you to plan material requirements for a manufacturing or procurement process.

MRP calculates gross requirements for the highest Bill of Materials level based on sales orders and independent demands. It calculates gross requirements at the lowest Bill of Materials levels by carrying down net parent demands through the Bill of Materials structure. The dependent levels might have their own independent demands, such as sales orders and forecasts.

The results of the MRP run are recommendations that fulfill gross requirements by taking into consideration the existing stock levels and existing purchase and production orders. The MRP run also takes into account defined planning rules for Order Multiple, Order Interval, and Minimum Order Quantity.

Recommendations are back scheduled by the defined lead time to arrive at the requirement dates for their own components.

Hi,

MRP is not material resource planning, but it is material requirement planning.

Following are the examples -

1) For material with MRP type PD - For these materials, when requirement is detected (while running MRP), either through sale order or project, system calculates the requirement, it's quantity & creates PR for procured materials. If source list & info record is maintained, then the source can be assigned to the PR.

2) For materials with MRP type VB - When the stock falls below the reorder point, the system creates the PR during MRP run.

Hi,

The main function of material requirements planning is to guarantee material availability, that is, it is used to procure or produce the requirement quantities on time both for internal purposes and for sales and distribution. This process involves the monitoring of stocks and, in particular, the automatic creation of procurement proposals for purchasing and production.

In doing so, MRP tries to strike the best balance possible between

optimizing the service level and

minimizing costs and capital lockup.

The MRP component (PP-MRP) assists and relieves MRP controllers in their area of responsibility. The MRP controller is responsible for all activities related to specifying the type, quantity, and time of the requirements, in addition to calculating when and for what quantity an order proposal has to be created to cover these requirements. The MRP controller needs all the information on stocks, stock reservations, and stocks on order to calculate quantities, and also needs information on lead times and procurement times to calculate dates. The MRP controller defines a suitable MRP and lot-sizing procedure for each material to determine procurement proposals.

Hi,

MRP is used to plan for production.

When you are working with Make to Order for each order what are the materials required to excute that oreder and what is the quantity and when they required is calculated by the system based on your configurations and Bill of materials.
