Cancelling / Removing a wrong Reversal expenditure Batch

Hi,

We have a scenario where there was an expenditure Item created through Pre-approved batch entry- the expenditure was distributed, accounted and later interfaced to FA.

Later by mistake ,someone created a Reversal entry for the Pre-Approved Batch which contained this expenditure Item.  The reversal batch has been released and the reversal entries have been distributed and accounted, though not interfaced to FA.The original expenditure was correct and was not to be reversed. Now is there a way( datascript being the last option) to cancel the reversal entry?

If not is there a some way I can make an adjustment at Projects without changing anything at Fixed Assets- the asset is created in April-2015 and has been depreciating correctly. So ideally we would not want to first interface the negative entry from reversal to FA and then again add another positive entry so the asset cost remains the same .
