The status of the change should only be changed by the member of the assignment group

The status of the change should only be changed by the member of the assignment group and the rest should not be changed until they are assigned to their group. After change is created and assignment group is assigned then if any one want to edit change request it should allow only that assignment group members.

I am unable to find that role raghav. I have checked before only about that role. I didn't find the security admin role

You need to get in touch with your system administrator, he can provide you security admin role.

Only user who have "security_admin" can give "security_admin" to other user. To give that role also they should be elevated first.
