Pass parameter values in a URL to Cognos Report

[Kikinho]

Hi there,

I'm Enrique, a developer in Cognos since 2 years ago and I'm working with Cognos Analytics 11.

I'm currently creating a report using a parameter as a filter for a query. (See attached document)
I'm calling to report from a URL with the parameter "p_ID_SIMULACION"

https://xx.xx.xx.xx/bi/?perspective=classicviewer&pathRef=.public_folders%xxxxxx%&action=run&format&prompt=false&promptParameters={"name":"p_ID_SIMULACION","value":[{"use":94}]}

In this way we are viewing the report. If you press "Edit" in the upper button, modify the report and return to view the report by clicking "Play" on the top, then we lose the value of the parameter we spent it in the URL and ask for it again.
How can I save this value parameter all time in this session?

Thanks a lot.

Regards :)
