Specify the list of data items for an object when you must reference a data item that is in a query but is not in the layout. For example, you want to add a layout calculation to a list that uses a data item that is in the query in its definition. If the data item does not appear in the list, you must reference it in order to make the layout calculation work.
You must also specify the list of properties if you
apply conditional formatting that uses a data item that is not in the
query.
Click the layout object that you want.
Tip: For a list of layout objects for which you can specify a list of properties, see the Properties property in Report Studio Object and Property Reference.
In the Properties pane, double-click the Properties property.
Select the data items you want and click OK.
