Projects are selecting sprints of other projects

[khushboo_puri]

Can we restrict projects to not select sprints of any specific project?

This behaviour is affecting scrum predictability measures.

Hello @khushboo_puri 

If I have understood your question, the short answer is no.

Sprints are not associated to Projects. Sprints are associated to Scrum Boards.

And natively Jira is designed to allow any issue to be assigned to any future or active  sprint, regardless of the board in which it was created.

There is no native method to limit the sprints that can be selected for a given issue.

Hello @khushboo_puri ~ in addition to @Trudy Claspill 's answer above, it depends to what you're referring ('predictability measures' as in reporting?).  If you're creating or editing an issue, in the Sprint field you have the option to show only sprints for the current project by unchecking the Show All checkbox.  If neither of these answers are sufficient, can you elaborate?
