 just a warning, but can some one explain what it means and how to fix it. (Appian 18.2)

Hi - Avoid exception timers on tasks that are prone to error or unexpected behavior. An exception timer is not a solution to a problem in a remote system. If your stored procedure times out so frequently that it's an issue, then it's that procedure and how it's used needs to be addressed. I suggest you review this post (all the way to the bottom). There are a number of details and illustrations therein that describe effective use of exception timers. An ideal use for an exception timer is on a user input task that should be completed within a specified time frame.

The Node named Cancel does not have an exit flow. Kindly please add some exit flows from the cancel node.

Can you double-check that the Cancel node is actually connected to the flow line going to the end node? The easiest way to check would be to drag the Cancel node up a few spaces temporarily.
