I have an issue with a cheque batch that did not post the correct balance to the bank account. The total of the cheque register is correct, but the AP-CK entry in the G/L is incorrect.

It is out by the amount of one particular cheque. That cheque has been cleared through the bank so my bank balance is out by this amount. I can do a manual entry to fix this, but as I am very new to using this system, I'm not sure what the repercussions would be to doing this. I would think that something in the back end might be out of balance.
