configure purchase minimums for vendors in Planning worksheet Nav 2009

Hi All,

Does anyone know if there is a way to configure purchase minimums for vendors in Nav 2009?

For example,

I have set up Item card with :

Manufacturing Policy: Make-to-Stock

Replenishment System: Purchase

Reorder Policy: Fixed Reorder Qty

Minimum Order quantity: 100

Reorder Point = 0

Reorder Quantity = 0

Safety Stock Quantity = 0

I have a Production BOM (BOM A), with 1 component (PartA), the qty per is 1 pcs.

I created a Sales Order (BOM A), the order qty is 2 pcs.

When I running planning worksheet, System suggest me to purchase 2 pcs only, It should suggest me to purchase 100 pcs (because of minimum order quantity setting).

Please help

Many Thanks
