Check the Balance sheet account config in AO09 it should be as attached.
I assume u have maintained following accounts in depreciation accounts in AO90
Acc.dep. accnt.for ordinary depreciation
Expense account for ordinary depreciat.
Take care of the Asset value date, complete retirement or percentage retirement while entering asset details in F-92.
I think if done all this u should get desirable result.
