Thanks Maciej.
See what I am looking to achieve is for a manager to be able to view the tasks of the employees he is senior to.
Eg. Say there is a group called manager with 2 users, manager1 and manager2. and There is another group say employee with 2 users emp1, emp2. Manager1 is manager of emp1 and should be allowed to view his tasks. and same for manager2.
So is there a feature to maintain such mapping between group users?
The same can be achieved in IBM ProcessServer and hence is a requirement I need to work on. If not then I would need to maintain external mapping.
