R12 Absence Management function

Hi

I have noticed that the new R12 absence management function is no long a basic leave of absence function.  The function now calls a generic HR approval workflow process via the form parameters, rather than the old HR_LOA_JSP_PRC.

2 things spring to mind that I am trying to get my head round:  how can I now detect with workflow process is being called by this absence management function, if I wanted to switch on / off approvals or even tweak the workflow process?  how is this now detected in AME approvals?  I noticed that in AME the HR_LOA_JSP_PRC is still listed in the supervisor delivered rule.
