Crystal Reports Trying to refresh a report opened via OpenDocument

Message

   Hi, 

We have a Crystal Report A that opens Crystal Report B via opendocument with a few parameters passed. Once we are in Crystal Report B, we would like to refresh the report and change the parameters. Problem is the report doesn't display the prompt box anymore and looks like it just consumes whatever parameter has been passed during the first call to the report. I have tried several things like adding NAII, sRefresh=Y, etc. I have also checked the "Prompt the user for new values" checkbox in the CMC but still can get the report to refresh. 

Is there any other opendocument parameter, CMC settings, report settings I need to do in order for the report to display the prompt box and get the user to change the parms and refresh ? 

Here is the link

Appreciate any feedback.
