If you wish to cancel the leave request, this is how you do it.

  1. Go to leave application.
  2. From the menu, go to Reports > My Summary.
  3. Click on the magnifying glass button to view the leave request.
  4. Click on "Cancel Leave". An email will be sent to inform the approval manager that your leave request cancelled.

If you do not see the cancel button, probably the leave policy does not allow the cancellation, and you have to contact admin to cancel on behalf for you.
