running sub task in debug mode

Hi all,

I've a main task that has to be run first in which I've a run sub-task command. I've marked a break point at some point in main task and sub task as well my main task is running under the debugging mode but the sub task is not working in debug mode. How to run both the tasks in debugging mode simultaneously i.e; when main task calls the sub task, the sub-task should also run in debugging mode only.

Thanks and Regards,
Babjee Vangipurapu.
