If the question is how to link from one report to another...then OpenDocument function can be used.
You can do this in different methods:
In ASP environment..
Universe level: create an object with Object format: HTML option enabled,
SELECT:<A href="Server:PortNo/wiasp/scripts/opendocument.asp?....etc..." >
Report Level: use Hyperlink function
Hyperlink("Server:PortNo/wiasp/scripts......etc..........." , "TaxtAsLink")
For JSP environment, replace ASP with JSP.
Any of the above methods will create a Hyperlink in the report pointing to Another report. The arguments/prompts for this new report can be passes from the original report.
Thanks,
