Hi Sunny,
I mentioned about the activation switch point in my question,and I can change valid from and to in gui screen as u said.
But once I do this setting I am still not able to edit the valid from and valid to dates in Webui which is important for me bcoz my users will be on Webui screen.
Can u tell me how to check the custom code maintained to grey out this field.
Regards
Jaya.
