UI5 Screen navigation via BPM

Hi Friends,

I have a question on how to setup a UI5 or for that matter any UI navigation via BPM. We want to use PI/PO via BPM to retrieve information from multiple systems based on the selection criteria in the first screen and display the info on the second screen. For ex in the below process we have a UI5 screen where we enter lets say Sales Order Number and on submit it starts the BPM process that calls multiple automated activities(which are proxy calls to ERP and JDBC calls to legacy systems) in the background and we want to display the results of these two activities on the second screen. Question is how do we keep the session alive and navigate to the second screen. Any thoughts are highly appreciated.

Thanks,
