Submitting Concurrent Program through plsql package fnd_request in oracle apps( No Audio)

This is request set
It can be used in interface programs..
To do interface programs.. we need to run
1) sql loader program
2) interface program

But The requirement is Client wants to run A single program.. In that he need 1)sql loader program and 2)interface program

so we need to add sql loader program inside interface program using fnd_request package

Create or replace package xxtest
as
procedure main(errbuf out varchar2,retcode out number);
end;
/
Create or replace Package body XXTEST
as
V_REQUEST_ID NUMBER;
v_phase varchar2(100);
