Defining Excluded Owners

Excluded owners are principals excluded from processing a task in the process model.

Example Example

A purchasing order process model contains an “Order Request” task and an “Order Approve” task. The requester and the approver of the order should be different persons, that is the requester is excluded from processing the approval task.

End of the example.

You define excluded owners on one of the following levels:

Task level
Human activity level
Lane level

Prerequisites
