Defining agent for subsequent tasks

[Marques Rodrigo (RBBR/ASE61) *]

Hello Everybody,
 
We are currently working on a workflow for Trip Approval and we are =
facing
troubles when defining agents.
The approval may have many steps, depending on the total value of the =
trip.
We want it to work like this...
 
If there are several steps: The first one must be approved by the
initiator=B4s manager (no problem with that!), the second approval must =
be
done by the manager of the preceding manager...and so on...
We are using role 168 (Manager US) to define the manager. In the next =
step,
the agent (manager) found in the previous step should be passed to role =
168
again and so on...
 
The question is...
Where do we get the agent found in the previous role definition? Is =
there a
field in the workflow container that should have this value?
 
Thanks in advance for your attention
 
Kind Regards
Rodrigo Marques=20
