Asset revaluation

Hi ,

I have one task .if u have answer pls help me.

The task is we have 4000 no of assets in books. The depreciation was run upto October end. We need to revalue the assets w.e.f. April 06. This should be done on December 1st. The revaluation values are manually arrived. They are to be updated in the system w.e. f April 1st. And the depreciation also should get affected from April 1st on the revaluated values.

Can you think it over on this?

Thanks &Regards
