The Remove Money In Transaction option allows you to remove a Receipt that has been applied in error.
Click on the [Tools] menu and select [Remove Money In Transaction].
From the drop-down box, select the Receipt. Click the [Remove] button.
If the Money In transaction has resulted in a credit that has been applied to any invoices, the invoices will be listed and when you remove the Money In transaction, the credits will also be removed from those invoices.
