I created a build definition that is scheduled for every 20 mins and on the “JazzSourceControl” tab we have checked mark both the checkboxes(see the attached snapshot).

My understanding is that engine will  -

1.)    Fetch all the latest code checked in last 20 mins and copy it on the BF agent.

2.)    Once code is copied , it will start a fresh build.

 So, right now what is happening - , it is triggering the build every 20 mins , but not fetching the lastest code from my workspace.

Q-1 Any clue why it is not copying the latest code from RTC  to BF agent during successive builds  or what I am doing wrong ?

Q-2 For CI builds is it required that I have give some timings in the schedule tab or CI builds can also possible without configuring anything under schedule tab ?

I can't attach the screenshot as I don't have enough reputation .
