How to abort instance using a specific role

Question

I create a process using BPM studio 10g. I create a role named GDadmin and a participant named GDadmin. No activity or interactive activity is in the GD admin role.
In the BPM standalone 10g, I create a participant and role both named GDadmin. This user can abort the instance. However, if I login as GDadmin, the workitem table is empty.
I want to the GDadmin can view all current instances. This user can also abort the selected instances.
Which activity can be used to let the GDadmin view all current instances and activity as well as abort them?
Thanks a lot.

You could accomplish the abort of instances using PAPI, but the problem is most actvities are not abortable (nor should they be) and the PAPI call will throw exceptions when you try aborting it.
I use the logic shown below to both grab and abort instances in a single step.
The process has a Grab activity that this invokes automatically called "GrabAutomatic". This is the Grab that has "From all / To all" and its "Abortable" properties enabled. The GDAdmin role in your process would need a Global Interactive that has the logic shown below. You'd need to add a new participant ("AUTOCLIENT" in the logic below) that has the role assigned where the automatic Grab is located. Before running this logic, the Global Interactive that the GDadmin would invoke would present the user with a list of instances that the GDadmin would select. Based on the work item instances selected, this logic would grab and abort them in a single step.
