Lot-Sizing Procedures 
Use
Lot-sizing procedures serve to calculate the procurement quantities, that is, the purchase order and production quantities.
Integration
- You define lot-sizing procedures in Customizing for MRP in the IMG activity Check lot-sizing procedure.
- You assign the required lot-sizing procedure to the material in the Lot size field in the material master (MRP 1 view).
Features
Three groups of lot-sizing procedures are available:
- Static lot-sizing procedures
- Period lot-sizing procedures
- Optimum lot-sizing procedures
You can also use the short-term and long-term lot size to divide the planning period for the lot-size calculation into a short-term and a long-term area. Therefore, it is also possible to use a different lot-sizing procedure for calculating the lot size in each of these areas.
The last lot can be planned exactly, independent of the selected lot-sizing procedure.
