Lot Sizes with Splitting and Overlapping 
Use
You can determine whether a fixed or period lot size is divided into partial quantities and that these are to be produced at regular intervals that overlap each other.
This lot-sizing procedure is very useful if the actual requirement quantities that occur in the period or the quantity to be produced for a certain date are very large but production is only laid out for smaller quantities.
Integration
Splitting and overlapping are only possible for fixed lot sizes and period lot sizes.
Prerequisites
- In Customizing for MRP, you must determine in the IMG activity Check lot-sizing procedure whether the procurement proposals are to overlap in the future or in the past starting from the requirements date:
Fixed Lot Size with Splitting and Overlapping
- You have maintained the following fields in the material master (MRP 1 view):
- Lot size field: FS indicator for fixed lot size with splitting and overlapping
- Fixed lot size field: total order quantity
- Rounding value field: Partial quantities, into which the total quantity is grouped. The fixed lot size must be a multiple of the rounding value.
- Takt time field: The period of time that the procurement proposals are to overlap.
Period Lot Size with Splitting and Overlapping
- You have maintained the following fields in the material master (MRP 1 view):
- Lot size field: FS indicator for period lot size with splitting and overlapping
- Maximum lot size field: Partial quantities, into which the total quantity is grouped.
- Takt time field: The period of time that the procurement proposals are to overlap.
Features
The system generates procurement proposals for the rounding value until the fixed lot size quantity has been reached. The in-house production times overlap by the takt time.
