Hello there, SJ15.
You'll have to create a duplicate payment, then delete the original payment. Then, recreate the payment line in the reconciled deposit. Let me walk you through with the steps.
To create a duplicate payment:
- From the Customers menu, select Receive Payments.
- Create a duplicate payment for the correct customer.
- Select Save & Close.
To delete the original payment and recreate the payment line:
- From the Banking menu, select Make Deposits.
- Select the Cancel button at the bottom of the Payments to Deposit window.
- In the Make Deposits window, choose the Previous button until you find the deposit containing the original payment (that was incorrectly applied).
- Go to the Payments button at the top of the window to open the Payments to Deposit window again.
- Select the newly created payment, then OK to add it to the previously reconciled deposit.
- In the Make Deposits window, select the original payment.
- From the Edit menu, select Delete Line.
- Click Save & Close to automatically replace the original payment with the new payment, then Yes to the warning: "You have changed the transaction.
Once done, delete the original payment. Here's how:
- From the Customers menu, select Receive Payments.
- In the Receive Payments window, select the Previous button until you find the original payment.
- Select the Edit menu and select Delete Payment.
- Click OK to the warning: "Are you sure you want to delete this transaction?", then Save & Close.
