Different Base Unit of Measure for Inventory

Hi All,

I know we have the followings on item Card:

1. Base Unit of Measure

2. Sales Unit of Measure

3. Purchase Unit of Measure

I also know the inventory on the card shows up as whatever has been setup for BUOM.

To make it easier for conversions and calculations I set the BUOM up in the smallest unit (let's say grams).

We buy boxes in different weights 20kg, 30kg.

I would like to have the BUOM in grams but the Procurement officer like to see the inventory in boxes.

Is there anyway to have more than one unit of measure for inventory on the Item Card?

Please advise
