If you examine the property page of Workflow Demonstration, you see that it calls a selector function named WF_REQDEMO.SELECTOR. This selector function is an example PL/SQL stored procedure that returns the name of the process to run when more than one process exists for a given item type. The selector function in this example returns Requisition Approval as the process to run.

The Workflow Demonstration item type also has several attributes associated with it. These attributes reference information in the demonstration application tables. The attributes are used and maintained by function activities as well as notification activities throughout the process.
