We need to restrict linking in edit screen from source to destination in JIra cloud

Question

Assume that we have 2 issue types A and B

A issue will link to more than one B issues ( 1 to many)

B issues will link to only one A issue (many to 1)

and the link between A and B is "is fixed by" and the link between B to A is "fixes".

How we can restrict the linking in edit screen such that A issue will link to more than one B issues and B issues will only link to one A issue. Could you please help me in this solution it will be helpful.

Thanks

Hi, @thumuluru.shreya! 😊

Thanks again for your question - I tested this out using Automation Rules, and here’s what I found:

Unfortunately, Jira Automation doesn’t allow us to remove just the most recently added link - it can only remove all links of a given type, which isn’t ideal in this case. 😕

However, a good workaround is to inform the user with a comment when an invalid link is added.

Here’s how the rule can be set up:

🔹 Trigger: When an issue is linked, and the link type is "Fixes"

🔹 Condition: The number of issues linked via "Fixes" is greater than 1

🔹 Action: Add a comment to the issue, like this:

⚠️ This issue is already linked to another issue using the "fixes" relationship.

Only one "fixes" link is allowed per B-type issue. The newly added link to {{destinationIssue.key}} from {{triggerIssue.key}} is not valid.

👉 Please review and remove any duplicate links.

🛠️ If needed, you can make the rule even more precise by adding conditions to validate the issue types involved - for example, checking that the issue being linked from is type A and the one to is type B. This helps avoid false positives and ensures the rule only triggers in the right situations.

I hope this helps.
