Asset Reversal not possible in AB08

Hi

I settled AuC into asset using AIAB and AIBU. Asset to which it was settled has a asset class with status of AuC as "Line item settlement is not possible for asset "

Now i while settling i gave wrong asset value date. I want to reverse this asset. When i ran AB08, it gave error as asset 1000 100384 has no line item settlement.

So i changed the AuC status for asset class to "Line item settlement" and then again ran AB08.

Then also its not allowing me to reverse. Let me know how to reverse this transaction.

I am on SAP Ecc6.0
