Using Duplicate Details and Accounts - Forgetting to check Internet Expenses Enabled

Hi, when updating an existing tax rate code for a new rate using the "Duplicate Details and Accounts" button, the "Internet Expense Enable" flag is not automatically checked on the new rate setup, based on the original setup.  If this is not checked for the new tax rate (old tax rate expires and new one takes effect), what is the consequences?  In testing the system appears to be functioning as expected with no issues encountered.

We ran the query noted in Doc. ID 852315.1 and it included the tax rate code that was adjusted with a start date active of the first rate setup, with no End date.
