In the Search Results table it is not possible to select multiple WTParts and create a new Change Notice, Change Request or Problem Report. In the Actions menu there is only an option for creating a new Promotion Request.
Please add the option to create a new Change Notice, Change Request and Problem Report to the Actions menu of the Search Results table.
The requested functionality is already available in the Actions menu of a Folder Contents table, but not on the Search Results table. The functionality should be the same in both tables: the selected objects will be added to the affected objects table of the change object.
Please see the picture below which compares the Actions menus of Folder Contents table and Search Results table.
