WBS settlement to wrong Asset

Hello gurus,

One of the users have settled the WBS to wrong asset number instead of an AUC in period 11 of 2007 which has been closed. They want to rectify this mistake. But they do not want to open period 11 and reverse the settlement. They want to make the settlement to the correct AUC in the current period.

I tried doing transfer from Wrong asset to Correct AUC but it throws error as acc. dep account is not maintained for AUC. And also depreciation has been booked against the asset for period 11 and period 12. The year has not yet been closed. Please suggest solution for this. Points will be rewarded.

thanks
