i have a value prompt with 3 values, if user runs the report, he'll see 3 values with checkboxes....
now if user clicks on 3 values, multi-select, 3 values should pass to three different drill-target reports, and 3 reports should trigger.
i mean is it possible to have drill-through kind of functionality in prompt values ?
I don't think you could have a drill through to 3 different reports from a prompt. An alternative approach would be to have a single report with 3 pages and render variables based on the prompt.
You can create a Drill through link on Prompt page like you can add a text or some thing like that and pass ur prompt param value to your target report.
But like Chris said, you can't expect 3 Reports/CognosViewers running at the same time.
