MRP type

Please explain how the MRP type works please?

for some materials we have MRP type as ND at the plant level MRP area and for tha same material MRP type is showing as V1 for the storage location level MRP area.Does the palnt level MRP type override any lower level MRP type?

Does the plant level MRP type need to be set to ND(no planning) for the MRP to run correctly for MRP areas.

Thank you.

Hi,

If you have MRP areas activated in your system (client level setting), then each plant has an MRP area.

Any other MRP areas defined in a plant (for storage locations or vendors) are independent of the Plant MRP Area, consequently reducing the scope of the Plant MRP Area.

All MRP Areas are planned separately and have their own MRP settings so they do not rely on other MRP areas. They are planned in the sequence defined in the Scope of Planning.

Example,

Plant 0001 represents a service business that reconditions equipment, consequently it has three different stocks for the same component (new, used and reconditioned). These are represented by three storage locations:

RM01 Used

RM02 Reconditioned

RM03 New

The latter two are used in preference to new parts (as they are much cheaper) but cannot be procured - they are only available if a machine is stripped down and the part is re-usable (RM01) or can be repaired (RM02).

An MRP area for RM03 is created so that there are two MRP areas: 0001 and 0001-RM03.

Stocks in RM01 and RM02 are part of the plant MRP area but cannot be planned so in this case the plant level MRP type is set to ND - no planning.

It is impossible to forecast consumption of new parts so the MRP type in MRP Area 0001-RM03 is set to V1. Obviously it would also require procurement type F, a reorder point, fixed lot size, lead-time, etc.

Whenever a new item is issued, stock levels are checked and replenishment is planned when the stocks reach the re-order pt.

Hope that answers your question

MRP Types

You use the MRP type to control which procedure is to be used to plan a material and which MRP parameters can be entered when maintaining a material master record. The MRP type is saved in the material master record.

The following MRP type parameters are relevant for the planning run:

MRP procedure

The MRP procedure determines which of the following MRP types is to be used:

1)MRP

2)Consumption-Based Planning (reorder point)

3)MPS

Indicator: Plan regularly

This indicator determines that materials that are given this MRP type are to be planned in regular intervals, even if no change relevant to the planning run has been made.

For materials that are to be planned regularly, you must also define the interval according to which the material is to be planned. You maintain this information in the MRP group.

For more information on this subject, please refer to the section, "Define maximum MRP interval".

Proceed

Indicator: Roll forward

To adjust the firmed master plan to a changed requirements situation, you can maintain an indicator for the deletion of old, out-of-date planned orders.

This indicator causes the system to delete firmed order proposals that lie before the so-called roll forward period in the planning run and to create new, scheduled planned orders (or depending on the fixing type they may be displaced to the end of the planning time fence).

You determine the roll forward period in the step entitled, "Define planning time fence".

For more information on this topic, refer to the section entitled, "Define planning time fence and roll forward period".

Proceed

Indicator: External requirements

This indicator is only relevant for reorder point planning. It can be used to instruct the system to include customer requirements and manual reservations in the MRP calculation for materials that are planned by reorder point. If a material is planned with this type of reorder point planning, then an entry is created in the planning file when creating or changing a sales order or a manual reservation.

If you want to include requirements in the MRP calculation in addition to the customer requirements and manual reservations, select the following fields:

Requirements for materials to be provided in subcontracting

Dependent order reservations on the basis of production orders

Dependent order reservations on the basis of maintenance orders or networks

Release orders

Purchase requisition releases

Forecast delivery schedules

Please note:

The system only displays the Include external requirements indicator if reorder point planning is selected as the MRP procedure.

Forecast indicator

You use this indicator to determine whether or not the forecast is to be carried out.

Forecast consumption indicator

You use this indicator to determine which consumption values are to be used in the material forecast.

MRP indicator of the material forecast

You use this indicator to determine which requirements values are to be taken into account in the planning run.

Calculate safety stock

You use this indicator to determine whether the safety stock is to be calculated automatically. The safety stock can be calculated automatically for materials planned with one of the consumption-based planning procedures if the service level has been maintained in the material master record, if historical data exists and if the forecast has been carried out for the material.

Indicator, calculate reorder point

You use this indicator to determine whether the reorder point is to be calculated automatically. The reorder point is calculated for materials planned in this way if automatic reorder point planning has been selected, if historical data exists, and if the forecast has been carried out for the material.

MRP list: extended header

The screen sequence key controls the display of the extended header in the evaluation screens for material requirements planning. That is, you use this key to control which screens are to be displayed in the extended header and the sequence in which the screens are to be displayed.

For more information on this topic, please refer to the section entitled, "Screen sequence for extended header" (MRP list + stock/reqmts list).

Proceed

Default settings

In the standard SAP system, the following MRP types are determined, for example;

VB => Manual reorder point planning

VM => Automatic reorder point planning

V1 => Automatic reorder point planning including external requirements

V2 => Automatic reorder point planning without external requirements

VV => Forecast-based planning

ND => No planning

PD => MRP

Reward if Useful.

Hi

MRP Type From KW

The MRP type is a key that controls the MRP procedure to be used for planning a material.

The MRP type belongs to the plant-specific data (in other words, the MRP area data of a material).

The MRP type controls which planning parameters must or can be entered when maintaining the material master record.

You can customize the parameters of the MRP types delivered with SAP R/3 according to your own requirements. You can also add new MRP types.

MRP Type From SAP Help Menu

Key that determines whether and how the material is planned. You have the following options:

Manual reorder point planning

Automatic reorder point planning

Forecast-based planning

Material requirements planning with forecasts for unplanned consumption

Master production scheduling (MPS)
