In a bound report, the main report is linked to a table, and sub reports are used to display information related to the data in the main report. The information provided in the main report is used to determine what information is displayed in the sub report.

 

If the sub report requires parameters then they are passed to the sub report from the main report using the Passing and Receiving properties found on the Properties Pane for a sub report component. More than one parameter can be passed to a sub report by separating the parameters with semi-colons. The Passing and Receiving fields contain one-to-one mapped values for the parameters; for every expression in the Passing field, there must be a matching parameter in the Receiving field. For more information about parameters and reports, see Chapter 14: Working with Parameters.

 

If the sub report does not use parameters, the data shown in the sub report can still be customized using the Filter By property for the sub report component. This second method makes it easier to re-use individual reports, as the sub report data shown is determined by the report using the sub report, and not by the sub report itself.
