BI publisher interactive format drill down
I am attempting to get a drilldown functionality working in BI publisher, so I can click on a user name cell in a table on the master report, which then opens another report with details on it. I have tried following http://bipconsulting.blogspot.com/2010/02/drill-down-to-detail-or-another-report.html and putting the url for the detail report in the URL field in the layout editor but the {ISO} doesn't seem to be passing the value of the clicked on cell to the parameter in the detail report.
Has anyone done drill down before in the interactive layout editor?
cheers
Tim
