Not for the *same* item, but I do have for example
STONE Bulk with UOM 1LB and
4LB Stone with UOM each
The Bulk stone is my purchased inventory and the 4LB Bag is a Manufactured Item.
Here is the general flow of a given Raw Material:
1) Buy 50lb box of Lab Stone (Supp Unit 50lb Box, Conversion factor 50)
2) STONE Inventory Level becomes 50
3) Sell 5 Units of Stone Bulk
4) STONE Inventory Level becomes 45
5) Get an Order for 3 4LB Bags of stone
6) Manufacturer 3 "4LB Bags"
7) STONE Inventory Level becomes 33
You can have different versions so long as you can manufacturer the secondary items.
