Dynamically adding *possible* agents to a task

[Nicholas Brand]

Memo from Nicholas N Brand of PricewaterhouseCoopers

Hi,
 
Here's an interesting problem:
 
I'm building a travel expense approval workflow.
Up to 3 managers may have to approve a claim.
We want to restrict the people to whom each manager can forward the
approval workitem to those managers ahead of him in the approval chain.
This will obviously vary with each claim.
 
I've found that the group of users that a workitem can be forwarded to is
based on the *possible* agents of the task (as opposed to the responsible
or selected agents).
 
Here's the question:
How can I dynamically set the *possible* agents for a task?
 
I've found various function modules that allow me to set the selected
agents or to retrieve the possible agents of a task, but not one to *set*
the possible agents.
 
Any clues or suggestions either on this approach or an alternative way that
you may have used?
 
Thank you for you time.
 
 
Kind regards,
Nicholas Brand
