I want to edit the resolution of existing issue (Fixed to Re-Open), but when i tried "Bulk operation -> Edit Issue" resolution field is not available on the screen that the edit goes through, can any one help me on this
You commented on another question which was essentially the same. There's two parts to an answer on this one (one or both parts might be a problem for you). The first answer over there is one part of the answer, and there's a link to fixing the second part at the bottom.
Re-read https://answers.atlassian.com/questions/118825/how-to-edit-the-resolution-of-the-existing-issue-in-jiralooking for my answer, but probably more usefully for you the link given by John Garcia.
