We recently upgraded to SD 14.1 and this feature is no longer avaliable. Apparently it was removed due to an issue when a user was creating a change order from a incident or problem that already had a CI attached. The software was allowing the same CI to be attached. In order to resolve this issue the button was grayed out in edit mode. This seems short sighted.
We would like to see this feature added back in as we feel it was a good feature and should be revisited..
