as you mentioned, this is a permission problem.
You have to open in your Console -> Administration -> User Management -> Roles -> Analyist with rightclick
the permissions für this role. Then in modules you will find Change Management and are able to activate this module for all of your analysts.
no, you have to double-click now on Process Related Object.
then you´ll get the permission configuration.
Correct answer was given by Support Engineer Philip Woodward in CASE 00822434.
This does then look like it is a privileges issue.
I suggest that you open the privileges and select the Change Module,
then use the Privilege wizard to set the privileges for you and select to clear child privileges as well.
