You use the MRP type to assign the procedure to be used to plan a material and to control which MRP parameters can be maintained for the material in the material master record. You enter the MRP type in the material master record.
The following parameters of the MRP type are relevant for MRP:
MRP procedure
| MRP procedure | Short Description |
| B | Reorder point planning |
| D | Material requirements planning |
| N | No MRP |
| S | Forecast-based planning |
| M | Master production scheduling |
| R | Time-phased materials planning |
| W | Replenishment (IS Retail) |
| X | Without MRP, with BOM explosion |
The MRP procedure defines which of the following MRP types is to be used:
- MRP
- Consumption-based planning (reorder point)
- MPS
The firming
type determines how order proposals are firmed and scheduled if you
work with a planning time fence in the planning run.
Configure Path:
SPRO -> Production -> Material Requirements Planning - Master Data - Check MRP Types (tcode OMDQ)
Key that determines whether and how the material is planned. You have the following options:
1) Manual reorder point planning
- While you are using manual reorder planning you have to maintain a reorder point manually in MRP 1 view of the particular material.
2) Automatic reorder point planning
- While using the automatic reorder point you have to maintain the forecasting view in material master and you have to give forecasting model. So here system will automatically consider the reorder point depending upon the forecasting technique.
3) Forecast-based planning
Steps:
a. Maintain Forecasting view in material master and enter
the historical data and forecasting period within the Forecasting view.
b. Maintain MRP type VV in MRP-1 view
c. Carry out MRP in transaction MP30 for Individual material
and MP38 for total Forecast at Plant level. The procurement proposals will
be generated
d. No PIR , NO sales orders r considered.
e. After MRP run, planned orders are created for the
forecast requirements.
4) Material requirements planning with forecasts for unplanned consumption.
Unplanned consumption is updated only for materials planned using MRP. This occurs in the following cases:
a. If goods are withdrawn from the warehouse without a
reservation.
b. If goods are withdrawn on the basis of a reservation,
but the quantity actually withdrawn exceeds the reservation.
5) Master production scheduling (MPS)
MPS is executed for selected material only based on business decision.
Maintain MRP TYPE as M0 to M4 based on your business requirement.
Use T-Code MD40 for foreground execution.
For background, create variant in MDBS and use this variant to create a job.
