Examples for Calculating Procurement Quantities and Yields
Example 1
Example Data
Net requirements |
20 pieces |
Lot size |
Lot-for-lot order quantity |
Scrap |
1% |
Process Flow
1. Define lot size |
20 pieces (estimated yield = receipt quantity in the stock/requirements list) |
2. Define scrap quantity |
0.2 pieces => rounded to 1 piece |
3. Add scrap quantity to lot size |
21 pieces (order quantity = order quantity of planned order) |
