Connected Query as datasource for BI Publisher report- how to set prompt values in PeopleCode

Hi, I have PeopleCode that pops up a BI Publisher report when a button is pressed, and that worked when the data source was a query. I used the code ( below ) to set the query prompt values. Now I want to change the data source to a Connected Query but I don't know how to set the prompt values. Could you help me find the right PeopleCode to do this?  My  Connected Query has two queries and they both have the same prompt (REQUEST_ID).

   Local PSXP_RPTDEFNMANAGER:ReportDefn &oRptDefn;

   Local string &ReportId = "UV_HRMOD50_R";

   Local string &TemplateId = "UV_HRMOD50_R_1";
