Filtering lines depending on descending queries

Hello,

In Oracle Reports Developer 11.2..0.

I want to suppress lines for which no details exist, meaning the descending query returns no lines.

As far as I understand group filters can not facilitate columns owned by groups below the current group - which is ok with me. But what if I want to filter lines depending on if a query below returns any lines. I want to suppress lines for which the detail query returns 0 lines. Is that possible and how?

Thanks,

Stephan
