Accessing the Filter Function

The filter function for work item, event, and process instance lists can be accessed either from the view definition, or from the list itself.

From the view definition - When you are creating or editing a work view, event view, process view, or data view using the view wizard, a Filter dialog is displayed from which you can filter the contents of the view (for information about creating/editing views, see Views). Note that if you specify a filter in this way, it becomes the base filter for the view — for more information, see Base Filter and Refined Filter.
From the list itself - Click the button, or select Filter from the View menu on the work item, event, or process instance list (when viewing a case reference list, there is no filter available; they can only be filtered from the data view definition). Note that if you specify a filter in this way, it is considered a refined filter for the view — for more information, see Base Filter and Refined Filter.
