Administrator (system) account will have all the rights in OVSD. The problem of read-only is due to roles. Please check the accounts you are using has proper roles configured. The access (View, New, Modify, and Remove) can be restricted at: Object level (Incident, Problem etc) Folder level (example â Internal or External) Field level (example Status, Description)
Agree with above statement about roles. Especailly if you have "limited status" for various roles. IE: if you don't want your users to update a "closed" item, you may have limited their role to the status just prior to closed.
My company had a situation where one of the Smart Actions for copying a Change from another change was not working. The reason was the change the user was trying to copy was closed and they didn't have access to update that closed change.
