CATS workflow agent assignment?

Hello everyone,

My scenario is as follows

In CATS data entry profile i made the following settings

With approval procedure

Using business workflow

Auto determination of a recipient

Task ID : TS31000007 - approval by a chief (supervisor)

Now i make the task as general task ( possible agents).

I dont define a rule for the task in the defaults tab .

Now does the workitem go to all users?

and if i maintain agent assignment to a task through PFTC ( for example i assign the task to a user) and dont define the rule .

Does the work item goto that particular user only?
