MRP does not respect Lot Size and Order Multiple

I have Lot Size set for Production Order items and Order Multiple set for Purchase Items.

I put a sales order for a finished good into the system to drive demand.

When I run MRP, it suggests (Purchase and Production) orders with the exact size needed to fill the order, NOT a full lot or multiple as specified on the item card.

I have tried a variety of planning paramesters and re-ordering policies without sucess.

Suggestions?

    Lot Size Field
    This field contains the quantity of the item that is usually produced in one production lot.

    If the item routing includes fixed costs such as setup time, the program uses the contents of this field when it calculates standard cost price and distributes the fixed costs of manufacturing the item.

    In addition, if you want to use the Dampener field to limit action message proposals involving insignificant quantities, you set up the field as a percentage of the lot size.
    - nothing about that production will be rounded or something to this size multiples...

    You can't use Lot Size as Kine says, but order multiple in kombination with reordering policy Fixed Reorder Qty. will work.

    I have tried this, and the Planning Worksheet still generates proposed order lines with fractional purchases. Any other suggestions?

    Manufacturing policy should be make-to-stock. If it doesn't work pls provide with more info version and other parameters on the item card.

    Yep tell us all the settings relevant on the item it is very difficult to guess what the issue could be.

    Are you using SKU's?
