Clearing Open Items In G/L Account

FI Gurus,

I need to clear some entries in a G/L account, the account does not equal to zero, as it is a clearing account use for accruals, got goods receipt. However I have all items open, I need to get a detail of only items that are truly open.

Does anyone knows which transaction to run? I have use f.13 automatic clearing, but since the account does not equal to zero it does not work.

Any Ideas will be appreciated.
