We have defined an implementation link type "is implemented by" / "implements", i.e. a parent is implemented by its children and a child implements a parent. I need to find all issues without a "implements" link (i.e. they don't implement a parent issue), but this issues may have their own "is implemented by" link. How to do that?
We have install ScriptRunner, so we have additional query functions like "hasLinkType". The following filter finds all issues without an implementation link.
issueFunction not in hasLinkType(Implementation)
But this filters out issues with a "implements" link as wel as issues with a "is implemented by" link. So those as issues without a parent and without children. But we want to find only the issues without a parent, i.e. without the "implements" links; they may have a "is implemented by" link.
