Sub report linking definition based on result, not on parameter value

Dear all,

I have created a report with CR 2008 SP6. The parameters from the referring BI query are period and customer. After the user enter parameter values, the report provides then Customer and product information.

I have add a sub report with additional information for product. I can transfer the parameter value (user input) for Customer to the sub report, but not for product, due to the fact that in the main report Product is not selected as parameter, but is a result set after the report is executed.

Is there a way to define in the Sub report linking exactly these result values of Product as new parameter for the sub report.

In the sub report linking definition I only see the possibility of defining the parameter as linking object, but not the report result set. See also the screenshot.

Any idea would be great. Best regards,
