Fixed order quantity

If you use a fixed order quantity for a particular item, every order for that item will have the same order quantity. If you require a larger quantity, LN generates multiple orders for the same item and the same due date.

Example
Example 1: Reasonable values
Demand2000
Fixed Order Quantity100
Result20 planned orders with quantity of 100

 

If you have a high volume demand and you choose a small fixed order quantity, LN generates many planned orders.

Example 2: Extreme values
Demand100000
Fixed Order Quantity10
Result10000 planned orders with quantity of 10

 

To define a fixed order quantity for manufactured items, use the Fixed Order Quantity field in the Items - Ordering (tcibd2100m000) session.

To define a fixed order quantity for purchased items, use the Fixed Order Quantity field in the Item - Purchase Business Partner (tdipu0110m000) session.

The Plan Items - Optimized Lot Sizes (cprao3110m000) session calculates the optimal lot sizes.

During the planning process, LN stores the requirements and planned orders for each individual plan item in memory. If requirements are very large, but the lot sizes are very small, the planning run requires considerable performance.
