Compensation - HR admin - what he can do during approval workflow

Content

Hi all,

I would know all the ways of involvement of HR during the approval workflow process in Compensation.

Can HR administrator intervene in each step of approval workflow? Can HR admin operate some changes after the second-level manager approval?
Who have the permission to withdraw the document? 
After the withdrown, the HR admin can operate again some changes?

Can you explain me all possible scenarios of changes effected by HR admin during each step of approval process?

 

Thank you so much for your support.

Kind regards,

Alessandro
