If you would like to have multiple versions of the same Material Item in your Item Catalog (ie. different units, prices, vendors, etc.) you can create a Copy of a Material Item in your Materials Catalog instead of having to manually enter a new one.
When viewing your Materials list:
- Click Copy (far-right of the table)
- A new box opens up titled "Copy Material Item"
- Edit any fields you wish to update
- Press OK
