Hello Norman,
Thank you for your reply.
Sorry for late response.
1. Yes, I see that this comes only for privilege/role which already have future assignment (or no validity to and from) for the user.
If I could get custom confirmation message then I think I would not get "No data was changed" message.
I am using IDM 7.2, SP8.
2. I had tried with NoCache also and this issue continue to occur even after days.
Regards,
Pradeep
