Two cash receipts have been assigned the same ID number
MYOB Accounting Plus allows you to assign the same ID number to multiple cash receipts.
If you didn't intend to assign a duplicate ID number to the second receipt and you wish to change it, locate the receipt in the Bank Register window or the Transaction Journal window and click the zoom arrow. The transaction will appear in the transaction entry window where you originally entered it. Depending upon how your preferences have been set, you can either edit the ID number or reverse the transaction and reenter it with the correct ID number. (Choosing changeable or unchangeable transactions)
