how to cancel a schedule concurrent

Hi experts
Could you tell me how to cancel a schedule concurrent.

I schedule a concurrent by the following steps

1. System Administrator
Concurrent->Requests

Submit a new request
Choose a Request, then click Schedule button
tick [Periodically], input value to start at  and end at
Re-run every 1 Days
click OK button
then submit the request.

By clicking [cancel Request] button, May I cancel the schedule concurrent, and make it don't run every day?

Thanks&Regards
