Why does the icon in the Requires Setup column show read-only?

If you don't have permission to perform a setup task, then the Requires Setup column shows read-only to inform you that a functional area or feature requires setup before the related transactions can be performed.

However, you can't use the icon to go to the Setup page to manage setup data since you don't have permission. Contact the person with permission to set up the functional area or feature before you start processing the related transactions.
