Validate linked issue types

Question

I am looking for a way to ensure only the proper link types are used between issues types/projects in JIRA. For example, a product defect blocks a client bug, not the other way around. I have not been able to find a way to add rules to limit the user's options. Any suggestions on how to accomplish this?

Hi Scott,

this is reported on Atlassian JIRA:

https://jira.atlassian.com/browse/JRA-9634

It seems that this issue is not going to be delivered soon. You can try Extended Schemes for JIRA to fulfill your needs. It covers not only Schemes for Link Types but for Priorities and Resolutions too.

Yes, you should be able to create a screen with (just) the field "Linked issues" on it.  The validation can kick in on the "validators" part of the workflow (although you'll want to do that on other workflow actions too)

Thank you Nic.  Yes, outside of our process, it's perfectly valid that a client bug can block a product defect.  However, we've implemented policy to exclude other scenarios.  I am just trying to find a way to enforce that policy in JIRA.

We are running JIRA v6.3.15.  Is there a way that I can create a workflow transition (eg. New to New) with a transition screen showing only the issue links.  Then use a validation to ensure the links adhere to policy?  If so, is there any guidance on how to implement this?  I'm still a scripting novice.
