hi,

The control parameters include:

Planning run type

You can choose whether all materials are to be planned or only those with MRP relevant changes.

NEUPL - its for total planning...

NETPL - Planning in PLanning horizon

NETCH - net change planning

Mostly we go for NETCH or NETPL...NEUPL is only used in case of planning for first time..Actually NEUPL is not used frequently because it cause lot of strain for full database for planning...

Creation indicator for procurement proposals for materials that are procured externally

You can choose whether planned orders, purchase requisitions or schedule lines should be created for materials that are procured externally.

Here as per your requirement you define whether you want any doc. to be generated or not...

Creation indicator for MRP lists

You can define whether MRP lists are to be created. IF this indicator is maintained then side by side the plannig will create the MRP list...

Planning mode

You can determine how the system is to deal with procurement proposals (planned orders, purchase requisitions, scheduling agreement lines) from the last planning run, which are not yet firmed, in the next planning run.

Scheduling

You can choose basic date calculation or lead time scheduling.

hope it helps...

Dear,

As soon as a material master record is created with MRP views. It is updated in the planning file automatically. The first step in Material Requirement Planning (MRP) is the checking of the planning file. The planning run (T. Code MD02 & MD03) and the scope of the planning run(T Code MD01) are controlled by the planning file.

The planning run type determines which materials are to be planned:

Regenerative planning (NEUPL)

Under this planning run the system plans all the materials that are contained in the planning file

Net change planning (NETCH)

Under this planning run the system only plans materials that have undergone a change relevant to MRP since the last planning run.

We choose the required planning run type (NEUPL or NETCH) in MRP Control Parameter (Processing Key) at the initial screen of the planning run itself. It is available under all the Transaction codes (MD01, MD02 & MD03). In addition, the following parameters also play vital role in planning.

Processing key Create purchase req. Delivery schedules Create MRP list Planning mode Scheduling Planning date

Process Flow

The system carries out the following processes in the planning run:

1. The system checks the planning file. During this process, the system checks whether a material is to be planned due to a change relevant to MRP, and how to proceed if there are already existing procurement proposals.

2. The system calculates net requirements for every material. For this calculation, the system checks whether the requirements are covered by the warehouse stock and dispatched receipts from Purchasing or Production. If the requirements cannot be covered, the system creates a procurement proposal. If a material has been assigned a range of coverage profile, the dynamic safety stock is also calculated during the planning run using the range of coverage profile. This ensures sufficient material availability even for unplanned additional requirements.

3. The system calculates procurement quantities. When doing this, the system takes into account the selected lot-sizing procedure and, if necessary, scrap and rounding values

4. The system carries out the scheduling in order to calculate the start and finish dates for the procurement proposals

5. The system determines the type of procurement proposal. Dependent upon the defined setting, planned orders, purchase requisitions or delivery schedules are created by the system for a material. If you have maintained the necessary entries for quota arrangements, the system also determines the source of supply and allocates this to the procurement proposal.

6. For every procurement proposal of an assembly, the system explodes the BOM and determines the dependent requirements.

7. During the planning run, the system recognizes critical situations that have to be assessed manually in the planning result by the work scheduler. The system creates exception messages and, if necessary, checks rescheduling. The system also calculates the actual range of coverage and the daysu2019 supply and receipt daysu2019 supply.

The planning run is usually carried out at plant level. In addition, the following are also possible:

Storage Location MRP Planning with MRP Areas Multi-Plant/Site Planning

Various control parameters are available for the total planning procedure and for single-item planning, which you can set in the initial screen of the planning run.

You use these parameters to determine how the planning run is to be executed and which results are to be produced.

Features

The control parameters include:

Planning run type

You can choose whether all materials are to be planned or only those with MRP relevant changes.

Creation indicator for procurement proposals for materials that are procured externally

You can choose whether planned orders, purchase requisitions or schedule lines should be created for materials that are procured externally.

Creation indicator for MRP lists

You can define whether MRP lists are to be created.

Planning mode

You can determine how the system is to deal with procurement proposals (planned orders, purchase requisitions, scheduling agreement lines) from the last planning run, which are not yet firmed, in the next planning run.

Scheduling

You can choose basic date calculation or lead time scheduling.

Hi,

Logic Used in Single-Item Planning

In single-item planning, only the settings from the initial screen of the planning run are used. The Customizing settings for the MRP group have no effect.

IN MM03.

Check MRP Type -PD, MRP Group - External Procurement, MRP controller in MRP1 view.

And Procurement type in MRP2.
