I want to open case in review mode. If there are any open assignments on this case, the list of assignments should not have a 'begin' link. In other words in this case review mode, you should be able to see list of assignments but not able to open the assignment from here or process the case.
The case list report, for the case id, I added a link and action set. The options 'Open selected item' or 'Open work by handle' both open case in perform mode.
