Workitem - Vanishes and capturing sy-ucomm

Question

Hello,
I have new to workflow area and have couple of questions. I have browsed through the documentation and could not get clear answers.
1.     I am sending a workitem to user, User is supposed to open it and approve/reject. If for user some reason does not do both and exit out of the screen workitems is vanishing from user inbox. How to fix this issue?
2.     I want to capture sy-ucomm from in the screen of workitem to workflow method and export it to next step. How to do this.
3.     Can I pass more than I parameter to my rule? If yes how and what code should I write to retrieve the values.
Thanks
Nani.

If your work item (step) uses a synchronous dialog task the work item is reserved when it is started, not completed.
Unfortunately SAP does not alert the application when the user closes a window using the window menu (or close button that you refer to). This should definitely have lead to some form of syst-ucomm, but it doesn't. I have had the same problem, and user training is the only solution. My experience is that the work item is reserved, as mentioned. My guess is that you have an asynchronous task without terminating events. This will be completed as soon as it is executed.
If you want behaviour to be different you have to either use an asynchronous task with terminating events, use a synchronous task or do some other trick (although I can't really think of any now).

Darn... just saw that your later update says the work item does not actually vanish. My comments are still valid though, but perhaps not as helpful as they would have been if I had answered sooner.
What you should do if the user doesn't complete his processing and leaves using the "Back" or "Exit" or "Cancel" menu options/toolbar buttons is to raise the cancelled exception in your business object. You do this by using the statement "exit_cancelled." The work item will then be kept in the user's inbox in a reserved status.
