Display the main report header in the sub report if the sub report opened in separated tab

I'm facing a problem in crystal report: I want to display the main report 开发者_运维知识库header in the sub report if the sub report opened in separated tab. Is there a formula or anything to do that.

I used :

Crystal Reports for Eclipse

Version: 2.0.1.r566

Can't you just add the main report header to the subreport's header?

As far as I'm aware, a subreport won't show the report header when it's a subreport, but will show the report header if it is run individually.
