I am facing a problem with the control key.
I am trying to change Network Profile (OPUU) (minor change - MRP cont.group); but while saving system is giving the error message: The control key "PS02" is not valid.
I have not changed any thing, and this setting is in system since last two years.
Also I have checked the Control Key definition, it is fine, not deleted or deactivated.
Can any one help me out on this?
Thanks and Regards,
