Note that if you reclass the invoices to another account, you will also have to do a GL adjustment when the invoices are paid.
If you are trying to create a $0.00 transaction in AR, you can enter a credit to sales and a debit to "recurring charge control account". The change to the customer account would be zero.
If you really need to test transactions, you can make a copy of your data and do the testing in the copy. Change the color in Company profile so you always know when you are in the copy.
