Purpose

Use the Parameters tab for informational purposes to document the name, description, and data type of parameters used in the report definition.

When a report definition is run within a workflow and is embedded in a section, an activity with a Property-Set method is typically executed before the report definition is executed, supplying values for the parameters. Then the standard activity pzOpenAndRunReport is called, passing the parameter page.

You can use parameters within the rule:

• on the Query tab to help establish data filters. Use the parameter on the left side of the filter condition, as in "where param.ThisThing > . pxThatThing".
• on the Data Access tab to help establish class joins or the data drawn from sub-reports. Follow the structure indicated above: the parameter goes on the left side of the statement.

For security reasons, report definitions to be executed on a web node as part of a Pega composite application cannot use parameters.
