There may be times when you need to change, delete or reverse a transaction you've entered into the MYOB system. When this is the case, you can choose to make changes to transactions entered in the Spend Money window so your records are updated properly. (You can make changes to transactions if your company file is changeable.)
You can also choose instead to quickly remove the effects of the transaction from your records by deleting or reversing the transaction. Then, if you want, you can enter a new, correct transaction to replace the transaction. If you want, you can make a few changes to the new transaction (such as the date and the memo), but you can't change the accounts and amounts that are associated with it. When you record the reversal, all account balances will be returned to their previous levels. (Whether you delete or reverse transactions depends upon whether your transactions are changeable or unchangeable.)
