We mentioned in the Inventory Items tutorial that RW Elephant allows you to include up to two customizable fields for your Items.
Users include these fields when they want to capture additional information about all or most of their Items. You might want to use these fields for the Original Manufacturer's SKU. Or perhaps keeping track of the warehouse location is important in your business.
Whatever it is, you can set it up in the Item Options section of your Account.
Navigate to the “Account” icon in the upper right corner of your browser window.
Click on “Item Settings” in the left column.
Click the green “Edit” button and type the labels you'd like for your custom fields.
Click green “Save” and you're all set.
These fields will now appear for each Item in your collection.
