Difference between task owner and initiator
Now you may have noticed while specifying the various task details that as well as
being able to specify the task initiator, we can also specify the task owner. At this
point, you may be asking what is the difference between these two roles?
The simple answer is the
task owner
has more administrative privileges when it
comes to a task. The
task initiator
is the person who creates a particular instance of a
task. Say, in our example,
jcooper
and
jstein
both request leave. In this case, they are
both initiators and can each withdraw the task they requested (but not
each other's).
On the other hand, the task owner may be the holiday administrator. They are
responsible for administering
all
leave requests. This enables them to perform
operations on behalf of any of the assigned task participants; additionally they
can also reassign or escalate tasks.
The task owner can either be specified as part of the task definition, or on the
Advanced
tab of the BPEL
Human Task Configuration
window.
If no task owner is specified, it defaults to the
system administrator.
When the task owner logs into the worklist application they will see an additional
tab,
Administration Tasks
, which will list all the tasks for which they are the
task owner.
Requesting additional information about a
task
Once assigned a task, sometimes you need additional information about it, before
you can complete it. In our example, the manager may need more information about
the reason for the leave request.
If a task initiator has been specified, then on the
Task details
form we have the
option of selecting
Request Information
. If we select this option we are presented
with the
Request More Information
form, where we can select who we want more
information from, and enter details of the information required (which will be added
as a comment to the task).
