Deleting work items?

Maybe I'm missing something, but it seems like I can't find a function to delete a work item from Jazz.

Is this possible? If so, how? If not, how are we supposed to remove work items that are simply mistakes?

Syed,

When I create a query with no filter parameters there are missing work items. I always assumed that they had somehow been deleted but looking at your response they they aren't. There are other WI set to Resolved / Invald which are visible. Do you know how to configure a query to be able to see all WI's.

Thanks
Mike

Thanks for the response Syed.
Ran the export & there are still missing WI - even in a sandpit project, where there are only 13 WIs some are still missing. The missing ones are system generated ones, 1 to 6 are visible (6 = Define the team members for the project area as well as the team area), missing 7 but 8 (user generated) is present.

Syed,
After creating a new project the first user created WI was assigned id=8, but id 7, which I assume was system generated, is not visible.
Within an active project how do I determine whether the missing WIs are system or user generated.
Thanks again for continuing this discussion.

Running a query with no filter criteria set returns:

13: test2
12: more tests
11: test2
10: test
8: user management
6: Define team members
5: Define categories and releases for work items
4: Define iterations
3: Share code with Jazz Source Control
2: Define a new build
1: Define an iteration plan

Is there another way to search for an WI other than generating a query ?

Thanks
Mike
