How to Schedule a concurrent program from Backend

We can use the same fnd_request.submit_request API which we use to submit a program for scheduling a program too. The only difference is the value passed to the parameter “start_time“.

Usually while submitting a concurrent program form backend we pass ‘sysdate’ as value to the parameter “start_time” but to schedule a program we just need to pass a future date and time to this parameter.

For example:- If you would like to schedule a program to run after 30 minutes from now, you need to pass “to_char(sysdate + 30/1440,’DD-MON-YYYY HH24:MI:SS’)” as a value to parameter “start_time“.

Note: 1440 is the number of minutes in a day.

Below is the example to schedule a concurrent program to run after 30 minutes:
