I'd like to configure the data card display to show one field only on the configuration card, but not on the @ card?
It's a bit odd, but you can pull it off. Create an input box on your card and tie it to a control variable (name it anything, it's just used to control the visibility of the BOM Description box) and set the default to anything that's not blank and exclude the @ configuration.
Then use a tab control that's controlled by that variable to hide or show the field. That should handle it for new files, you'll need to use dispatch to set the variables on existing files since defaults don't get updated. I've attached an example card.
