Year-End adjusting entries to Accounts Payable

Hello,

I know this is an old topic, but just wondering if someone could give some advises. I'm using Premium 2011, and the year end entries I got from the accountant is : Cr. 2100 Accounts Payable xxxxx,  Dr. Retained Earnings -Previous year xxxx
Simply won't allow to post journal entries to Accounts payables as it's a linked account.  how am I supposed to adjust that. hope someone can give a solution for this.

Thanks in advance.
