fnd_run_function.GET_RUN_FUNCTION_URL does NOT call the Oracle OM form with parameters

Hi,

We have a requirement to provide the ability to users to call the Oracle OM form directly with parameters from an URL, we were planning to use the fnd_run_function.GET_RUN_FUNCTION_URL to achieve this requirement. But when we have  the URL generated only navigates to the OM form but does not execute it for the header id we have passed.

select fnd_run_function.GET_RUN_FUNCTION_URL(14914, 660, 50272, 0, 'HEADER_ID = 9941792' , NULL, 126, NULL) from dual;

Could anyone please assist !

Thanks
