WRONG DATE ON CREDIT CARD RECONCILLIATION

Yes, exactly you can do that, Jt72.

You can undo each reconciled transaction one at a time to minimize the impact on your books if you want to modify the date.

Here's how:

1. Go to the Accounting menu.
2. Select Chart of Accounts.
3. Locate the account holding the transaction, hit the Account history link.
4. Select the transaction you want to unreconciled to expand the view.
5. Review the check column, if the transaction is reconciled, you'll see an "R".
6. To remove the transaction from reconciling, click the checkbox until the box is blank.
7. Once done, hit Save.
8. To make changes, you can select that transaction again and click Edit.
9. Make necessary changes on the transaction date, then Save and close.
10. Repeat the same process for all the transactions you wanted to change. Just don't forget to put an "R" after making some changes to have the transaction reconciled again.

Hi 

thank you for your help. 
If I delete all of the transactions will it cause any problems eg with the report ? (The report you can go into and look at , with all of the details of the reconciliation) 

Hello Jt72!

It'll cause discrepancies and will mess up your data once you delete the transactions. I'm here to further assist you in fixing your reconciliation.

Although it'll reflect on the Reconciliation Discrepancy Report that you deleted the transactions, note that you can't undo them. The best option is to manually unreconcile them, then reconcile them again.
