Oops! I made a mistake.
Cancel Transaction and Credit Note are both reverse entry but use differently. You use Cancel Transaction for correcting duplicated entry, and a Credit Note for adjusting the account.
It does not delete when you cancel a transaction; instead, it creates a reverse entry to correct it and forms an audit trail for the accountant. Unlike Credit Note, both the cancelled and cancellation transaction does not show on the GST report; therefore, you should not use Cancel Transaction as a shortcut for adjusting the account.
Although the journal behind the Cancellation and Credit Note is the same, the GST treatment is different. Consult your accountant if you are not sure of the method used. Use a Credit Note instead of a Cancellation if you are uncertain.
