This first portlet displays the states of all processes within a specific time interval.

The measure used is Process Instances, which shows how many instances of a

particular process have completed, failed, or are still running. A PresentBlox was

used that shows both the grid and chart of the same data. The number of failed

processes is shown in red, to highlight them. The user can customize the

appearance of reports interactively using the context menu of each report. The

report is shown in Figure 7-32.

As shown in Example 7-6, the portlet JSP defines a Data Blox that connects to

the cube, retrieves the appropriate data, and then supplies it to the Present Blox,

rendering it using both a Grid and a Chart Blox.

Example 7-6 Example of data and present Blox for displaying process states

<blox:data

bloxName="<%= dataBloxName %>" visible="false" dataSourceName="AuditCube"

query="SELECT DISTINCT({[AuditCube].[Process States].children})ON AXIS(0),

DISTINCT({[AuditCube].[Processes].children})ON AXIS(1)

FROM [AuditCube] where [Process Instances]"

...

</blox:data>

<blox:present visible="false" bloxName="<%=bloxName%>"

id="ProcessStatesBlox">

It is often useful to show the states of all the activities associated with a particular

process type. You can use interportlet communication to link the process states

reports with the activity states report. We added a hyperlink to each process in

the process states report in order to link to the matching activity states report.

The activity state report shows how many instances of the associated process

activities are in a given state. Figure 7-33 shows the activities states for the Claim

Process.

A hyperlink to each process is added by inserting the following code snippet into

the present Blox for the Process States portlet as shown in Example 7-7.
