Using Report-to-Report Interface (RRI) in BEx Report Designer?

Dear experts,

I would like to know if it is possible to use Report-to-Report Interface in BEx Report Designer?

From what I read from this article

[(Creating Formatted reports using BEx Report Designer)|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00ae5173-6112-2d10-d78f-e7779d269f25?quicklink=index&overridelayout=true], the RRI capability of query is not supported in BEx report. So is it true? And are there any workarounds to enable/emulate RRI capability in BEx Report?

Thanks in advance.

Regards,

Joon
