following example for my problem:
I try to define a main-report which several sub-reports. main-report contains for example article reference-data (article-No, article-name, ...). The subreport should contain sales-information.
I would like to start the mainreport with a parameter artikel-no and a time-period. The subreport contains as well the parameters article-no and timeperiod. The parameters of the main-report should linked to the subreport, so that I have to enter the parameters by report-start only once.
Unfortunately in my case, by report-start crystal expect the parameters twice: I have to enter article-no and timeperiod for both, for main- and for subreport. The normal subreport-linking doesn't work! With "nomal" relational databases I have done it for many times, but not in my case with a universe as datasource.

What I am doing wrong ????? Any idea ?
environment:
crystal report 2008
oracle-datawarehouse as universe-datasource
thanks for help !
