WorkItem Routing for HR

[Lisa Kapusta]

Hi All,
 
We are needing to route work items to a select group of users.
However, these users are not contained within the same org and
may hold different types of jobs as well - thus we can not use
the companies existing org structure for routing.   My questions
is how can we achieve this?
 It is my understanding that a stand alone org unit can not be
used as it would conflict with the PD org structure, reporting,
etc.  Also, we are not wanting to hard code and the positions
associated with these users will not be static.  Also, we are
trying to avoid any unnecessary maintenance of custom tables,
etc.  In previous messages I have read that  work centers may
provide what we are looking for - however, it is my understanding
that they will be using work center for other functionality.
Any suggestions?
thanks
Lisa
