Hello,
I have a scenario where we are running a sprint and end of the sprint there are still some stories are partially completed (and the story is still work in progress).
When I complete the sprint either I can move the story to next sprint or close the story in current sprint and open new story in next sprint.
1) If there are open items then I cant complete the sprint so I move the stories to next sprint
a) Developers are already worked partially on the story so the efforts spent on the previous sprint is lost if we move the story to next sprint
