The Account Historical Balances window should be displayed. (To find the Account Historical Balances window)
Exception: Your Current Year Earnings account
The balance of the equity account called Current Year Earnings is incremented automatically during the course of your normal MYOB AccountEdge business activity. As a result, you can't enter an historical balance for the Current Year Earnings account.
Warning: Historical balances affect the P&L accounts' opening balances displayed in this window
When you enter historical balances for income, cost of sales, or expense accounts, keep in mind that AccountEdge will change the opening balances that's displayed in the Account Historical Balances window for those accounts to reflect the historical entries you make.
If, for example, your fiscal year runs from January to December and your conversion month is July, you should have entered opening balances for your income, cost of sales and expense accounts that indicated those accounts' net activity for January through June. AccountEdge, however, considers the opening balances as June's historical balance, not the entire January-through-June time period. If you now enter historical balances for January through May, those balances will be subtracted from the June activity figure.
