## The Requisition Item Type

The Requisition process is associated with an item type called Requisition. Currently there are two workflow processes associated with Requisition: Requisition Approval and Notify Approver.

If you examine the property page of Requisition, you see that it has a persistence type of Temporary and persistence number of days of 0. This means that the run time data associated with any work items for this item type are eligible for purging as soon as they complete. You also 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 or 'Requisition Approval' as the process to run.

The Requisition 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.
