Use

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

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.

You define excluded owners as follows:

  • Excluded owners for a single task

  • Excluded owners for an individual human activity

  • Excluded owners for a lane

When you define excluded owners, the following override semantics apply: Lane → overrides → Human Activity → overrides → Task. For more information about role overrides, see Defining Task Owners.

Prerequisites

  • You have opened the Process Development perspective in the SAP NetWeaver Developer Studio and have expanded your project in the Project Explorer view.

  • You have assigned a task to the human activity in your process model. More information: Modeling Human Activities .

  • You have configured the AS Java in the Developer Studio to be able to search for users in the User Management Engine (UME). For more information, see Configuring the Application Server in the Developer Studio .

    You can refer to SAP Note 1445197 Information published on SAP site for more information about enabling secure communication with the AS Java.
