My requirement is to keep a link in a dashboard , which should open another dashboard or report .The linked dashboard will have a statistical table of data .The data should be based on the filter selection from parent dashboard.
If the token names are different on the target dashboard, you'll need to change the names accordingly. If you want the drilldown to actually come from a link and not a table, you'll have to change the link target to update on token changes. This could be done like this:
<a href="<url>/target_dashboard?form.foo=$foo$&form.time_tok.earliest=$time_tok.earliest$&form.time_tok.latest=$time_tok.latest$">Link to target dashboard with filters based on this pages settings</a>
You should refer to these docs for more detail. You are most interested in <link> and <drilldown>.
