Menu calling Report in 10g how can i do using RUN_REPORT_OBJECT

We have the applications in Forms6i & Reports 6i (Client Server) and migrating to Forms 10g and Reports 10g. We have the menu, from that menu we are calling all the forms and Reports. For especially Reports earlier we user RUN_PRODUCT but now 10g it is not working. How can call the report using RUN_REPORT_OBJECT

Important things we have some dynamic parameters (input) to the each report. That means when i called the report from the menu i need to get first parameter form to take the parameters and then can be run the report.
