Data fix to update Asset cost account after using it for some assets

Hi,

There was a typo error in picking Asset cost Natural Account in Asset Categories form for a book (Accumulated Depreciation was picked instead of Cost). Post  which, 10 assets had been added and Depreciation was run, period closed in both FA & GL. Now, user realized the mistake and wanted a data fix to update Category level accounts and to fix all accounting entries created wrongly for the last period. 

Thanks..
