QSWorkItem provides data for work items which are assigned and available to a user, including the work items delegated to them by the other users. Every request can optionally take a QSWorkItemFilter. The return type is a QSWorkItemRS that provides the scrollable ResultSet and the WorkItem SVO. The default sort order for the retrieved data is due date.
The APIs used with the delegated work items are called proxy APIs, which get available and assigned work items using query service support queues.
