Syntax sInstance=Param

Hi all,

I need to link my reports from Webi with openDocument, but i don't know the syntax to use sInstance=Param.

I tried to use:

="<a href=http://server:8080/OpenDocument/opendoc/openDocument.jsp?sType=wid&sDocName=TEST&sInstance=Param&lsSID=2>TEST2</a>"

In the syntax above, the child report TEST has a prompt ID, and i want to open the last Instance for the parameter ID=2

Can somebody tell me the syntax to use sInstance=Param?

Thanks in advance.

Regards,

Jorge Orozco
