Filtering a Process Instance List
Filtering a list of process instances involves entering filter criteria so that only some of the process instances are shown in the list, rather than all of them. Filtering a list of process instances allows you to display only the process instances you are interested in.
For example, you may only be interested in process instances that were started earlier then Dec. 15, 2008 You can filter the list so only those process instances are shown.
The filtering function allows you to build a “filter expression” that is applied to all process instances. If a process instance satisfies the filter expression (e.g., it was started earlier than Dec. 15, 2008), it is shown in the process instance list; if it does not satisfy the filter expression, it is not shown in the list.
Because filtering process instance lists is basically the same as filtering other types of lists in Workspace (with the exception of the specific fields on which you can filter), details of filtering is explained in a single chapter — see Filtering Lists.
