I need a spec code in the Financial Reporter that will give me the balance of an account at the end of last year, including any adjustments posted to the adjustment period.

Can anyone tell me if such a code is available?

Use the usual code for the ending balance Last Year - LY and then click on the icon that looks like the letter YE with a check mark behind them. That will include the figures from the YE adjustment period.

You could also use BAL_Y which is the opening balance for this year.
