deprn_reserve for fully amortized asset uploaded

Hi experts

I need your help please

in tax book, we have uploaded cost, accumulated depreciation into this tax book. those assets are fully amortized , hence Cost = reserve

but we would give customer file to verify whether this uplaod is ok or not.

I use the table fa_deprn_summary to extract cost and deprn_reserve, cost is ok but deprn_reserve is equal to zero. where can i find the real deprn_reserve that we have uploaded by FA tax interface.

Thanks
