I have confirmed with Quickbooks the you can't Reconciliate an account under the following conditions:
(Note I am using Quickbooks Desktop so I can't comment on other versions)
1 - Accountant's changes are pending
2 - The account in question does NOT had a field for Interest date, like Other Current Liabilities.
3 - There are open transactions before the Accountant's Copy dividing date
You will get a warning stating that the Statement date, service charge date and interest dates must all be after the Accountant's Copy dividing date of YYYY-MM-DD
As there is no interest date field for you to modify, the software's logic must be assuming a date, before the dividing date, and therefore will always fail it test.
This is a bug that Quickbooks was able to reproduce and is now sending off to their engineers, so who know how long it will take to fix.
