Define what is planned and unplanned consumption?
Unplanned consumption is updated only for materials planned using MRP. This occurs in the following cases:
1) If goods are withdrawn from the warehouse without a reservation.
2) If goods are withdrawn on the basis of a reservation, but the quantity actually withdrawn exceeds the reservation.
Planned consumption is not displayed in the material master record. However, you can calculate it yourself by subtracting unplanned consumption from total consumption.
The system normally updates the consumption values in the material master record automatically whenever stock is withdrawn from the warehouse.
Material requirements planning is carried out using current and future sales figures. Consumption-Based Planning uses past consumption data to calculate future requirements with the help of the material forecast or statistical planning procedures.
The consumption based planning means:
If you are planning your Raw Material not by MRP run, then use Consumption based planning with reorder point. For this the MRP type is VB. The system will not generate PR during MRP run. When ever you issue a RM the system will look for reorder point and if the stock is less than this it will run in planning file entry. The system will raise PR at that point of time only.
In which Tables can I find:
1. Consumption of material
2. Stock of material
1. Consumption of material: MARC - VMORD
MSEG – MENGE
S026 - ENMNG
2. Stock of material: MARD Table
Choose the following filed
- Unrestricted: LABST
- Restricted use: EINME
- Blocked: SPEME
- Return: RETME
- Max stock MARC-MABST
本文介绍了在物料需求计划(MRP)中如何区分计划内与计划外消耗,并详细解释了这两种消耗如何更新及计算。此外,还说明了基于消耗的计划方式,并提供了查找物料消耗与库存数据的具体表格。
