Delivery unit rounding to multiples

Dear Experts,

We have a business requirement here for setting a minimum order quantity and delivery unit for materials. The requirement is illustrated below-

Mat A,-Qty 2

Mat B - Qty 4

Mat C-Qty 3

The above shown quantity should be minimum order quantity and also the deliveries should only be in the multiples of the minimum order quantity.

We have tried using static rounding

Threshold val   Round val

1                         1

It works well by automatic substitution of MOQ, but  it does not seems to round of the delivery unit to the multiples. It just gives a warning message.

Can you please suggest how I can achieve the requirement of having order quantity rounded off automatically to the multiples of delivery unit.

whether static or dynamic can be used, if so exactly how to do it.

Thanks

Arun
