Help with error on reconciliation

Hi accounting, 

Let me provide some information about changing an incorrect date on a reconciliation.

We appreciate you carrying out my colleague's recommended solutions. We can still change the ending date if you haven't finished the reconciliation by returning to the reconciliation page. Then, modify the Ending Balance and End Date periods. Here's how it's done:

1. Go to Transactions on the left menu.
2. Click the Reconcile tab.
3. Choose the bank account from the Account drop-down list.
4. Tap the Resume reconciling button.
5. Tick the Edit Info button located in the upper right-hand corner.
6. Change the Ending Balance and Ending Date.
7. Press Save.

However, if the reconciliation has already been completed, the option to change the date is unavailable. However, you can reverse the reconciled transactions. Here's how:

1. From the Transactions tab, select Chart of accounts.
2. Locate the account for the transaction and click View register.
3. Look for the transaction that you want to undo reconciliation.
4. In the check column, repeatedly click the top line of the transaction until the box is blank. This removes the transaction from the reconciliation.
5. Click Save.

From there, you can start reconciling again. Here's an article as your guide: Reconcile account.

Moreover, I've added this article on how to prevent the system from any changes: Close books.

I'm always around whenever you have concerns about managing bank transactions.
