I have a problem in approval process in planning unit hierarchy. I created planning unit hierarchy. When I run approval process, ownership of the process moves to user, which specified in planning unit hierarchy as "Owner". When owner promote approval process to the next user "Viewer" and current position is at "Viewer" tha data couldn't be entered by Owner. But in my situation data don't close to enter at Owner, and he can change the data, which he sent to Viewer. It isn't correct. Why data don't close to enter at Owner, though the current position of approval process at "Viewer"?
