This Unclear option will allow you to remove the cleared date from a series of transactions in the Transaction History file. Normally you would never use this option, but if you use the wrong clear date as you reconcile the bank, you may wish to remove the cleared date and start over. You can go into the bank reconciliation option and click on every entry to unclear each entry, or you can run this option and unclear the entries all at once.
Be sure to select the correct bank account. The cleared date in the transactions must match the date entered above.
