Balance Adjustment

Hi All

I have a doubt, please let me know whether this is possible in SAP FICO.

During the year end, i have carried forward the balance of a balance sheet a/c to the next year but now i have come across an adjustment for that a/c. What should I do? That say for example, my balance sheet a/c is ABCD and i have carried forward the closing balance of that a/c XXXX as next year opening balance. now i have to make an adjustment to that a/c in the last year. Is it possible in SAP. If yes how?

Regards
