To present a summary view report to a user, your activity can call the standard activity Rule-Obj-SummaryView.ShowView. Through parameter options, you can choose to retrieve the data from the database and add it to the clipboard with or without displaying.
Specify one of four values for the pyAction parameter:
Prepare — Execute all aspects of the summary view rule except the HTML display. Refresh — Execute the entire summary view rule, retrieving data from the database, sorting and filtering the data, and presenting the display.Redisplay — Execute the display aspects of the summary view rule, using data previously retrieved.Sort — Resort the existing data. To specify that execution is to use a reports database (regardless of the setting of the Use reports database? check box on the Contents tab), set the pyUseAlternateDb parameter to true.
To remove the data page after the initial display (reducing the size of the clipboard), set the removeDataPage parameter to true.
To execute a summary view report or interactive chart when the user clicks a link, such as on a portal gadget, call the built-in JavaScript function showSummary(), which calls one of these two activities.
The older activities Rule-Obj-SummaryView.ShowGraph and Rule-Obj-SummaryView.ShowViewGraph. are deprecated.
Summary view rules can accept additional parameters for selection, by referencing them with the notation param.name in the Value column of the Criteria array on the Content tab. Ensure that processing sets values for these parameters before the summary view rule executes. For a similar example, see the PDN article How to use parameters as selection criteria in a list view rule.
The text of the Full Description field (property pyDescription) of a summary view rule on the History tab appears to application users as a report title. Choose text that clearly describes the report contents. You can include syntax in the Full Description to include at run time the value of a parameter or scalar property. For example:
List of {pagename.property1} as of {pagename.property2 }
Only refer to properties that are certain to be present. The valid formats are{Param.name} and {Page.property}. This feature can support localization, through language-specific RuleSets.
If your summary view rule calls a custom getContent activity, the activity can set property values that are then displayed in the title.
If your access group includes an unlocked RuleSet version, you can use the Customize View feature. Use the Customize View button to create a personal copy of the summary view rule, with your Operator ID as the last key part.
The summary view facility works best for queries involving 1,000 or fewer rows. It does not support queries that contain more than 10,000 rows.
To the extent possible, design summary view reports to maximize processing by database software (based on the Content tab) and reduce processing within the PRPC server.
DateTime values (but not Date or TimeofDay values) in the results are converted to display in the time zone of the user, based on the Time Zone value on the Availability tab of the Operator ID instance. This conversion affects selection criteria and displayed results, and so may present a different day and time for different users.
Using an agent and a Connect File rule, your application can produce PDF files of reports, on a regular schedule.

The immediate parent class of Rule-Obj-SummaryView and Rule-Obj-ListView classes is the Rule-Obj-Report-class. At run time, the system uses stream processing to assemble the query results.
