BI Publisher: How to pass the current query Result on UserInterface to a "Scheduled Report"

The VBC in the picture is "Report Schedule Parameter BC" and respective applet where I'm writing the code is on "XMLP Report Schedule Applet".

This is a vanilla applet where we schedule a BIP report on any relevant view.

The customization we are doing to implement email functionality is that by adding a new button in the applet and invoking "BIP Report Generation DeliveryChannel" workflow as per the instructions provided in the Oracle whitepaper (1425724.1).

Example: I've executed a query on Account List applet as [Name] LIKE "A*". Now I try to schedule & email the report which requires the same search spec to be passed as an input to the above mentioned workflow which is a challenge.
