Hi John,
I have a liitle doubt. As per the screen shot of the Asset master data, the useful life and depreciation start date are different in DA 01 and 02. So when you see the values in AW01N, do you get different values ?
Secondly, the useful life and depreciation start date in DA12 is same as DA02 and the customisation for Specify Transfer of APC & Dep terms have been kept as "Identical". It means system should transfer the same value as DA01 but as per the Asset master it'll be different since the useful life and dep start date is different. So I guess the values are contradicting hence system may not be showing any value.
Hence please try removing the Tick from Identical column for DA12 and execute ASKBN and see if there is any difference any result. I hope you are testing it in your Quality/Sandbox servers.
Thanks & Regards
Ramesh
