Hi Yenthe, Thanks for your replay I tried to use audittrial in v8 but when i try to use but generate exception object_proxy not found. I am also doing R&D and have any alternative object to use same functionality of audittrial? Thanks again for your answer.

Well.. this module has audit reports but I'm not sure if that is enough for you. See https://www.odoo.com/apps/modules/8.0/mgmtsystem/ It also turns out the module Audit Trial is back in the master (upcoming V9) so I'd give that a try too. See https://www.odoo.com/apps/modules/master/audittrail/

Thanks and i approve your answer for this question.

Thank you very much Harsh! Feel free to accept the answer too if everything works out. (Its upvoted now). Best of luck!
