You may create new dynamic parameters by adding a filter to a report or graph component in the layout.
The Filter options dialog box opens.
The New Parameters dialog box appears.
You may select a control type for the parameter from this dialog box, or adjust them later using the Settings panel on the Parameters tab.
If the New Parameters dialog box does not appear, ensure that Show New Parameters dialog is selected from the HTML Page tab. To access the HTML Page tab, select Options from the Window menu to open the Developer Workbench Options dialog box. From the Developer Workbench Options dialog box, select the HTML Page tab.
Repeat this procedure for each additional parameter for the report or graph.
