Passing real time binding parameter to OTBI as presentation variable

Content

I have a requirement to add OTBI report in Termination Page UI which will capture three Real-time Binding Parameters (Person ID, Termination Date & Termination Notification Date) into report through Termination Page. I have created Presentation Variables to capture Real Time binding parameters from Termination page UI.

Here main challenge is to pass parameter from page UI to OTBI as data isn't stored in the DB and I am displaying OTBI report before making termination transaction. I have attached detailed requirement document with this post.  

Is is possible to link this report in Termination UI through Presentation Variable? Is this requirement feasible? If yes then please post your suggestions.
