Q) How do I delete a sub-group, location, category, and custom field? A) All of these objects possess the property that they may not be deleted if in use by the system. Before you can delete any of these you need to edit all tickets that use it. First, view tickets in list view and filter by selecting the sub-group, location, category, or custom field name that you want to delete. This will show all tickets that contain an assignment to that sub-group, location, category, or custom field. Next, open each ticket and change its assignment. Next, go to Options/Manage Group and select the appropriate option. From within the screen select the item you want to delete. Click on the Delete link to delete the item. If the Delete link is dimmed this indicates that there are still records in the database that contain that item. Repeat the process until the link is no longer dimmed, then delete the item.
