Need a help in writing Automation Rule

I would like an automation rule ensuring that: If a number entered in the field "document number”, matches a number already entered in this field in an existing task, then the two tasks will be linked.

Document number is the custom field.


I have written a rule and its not working , can anyone tell me where I am failing?

Hi @Swati Mathapati -- Welcome to the Atlassian Community!

When you note the rule is not working, what do you observe happening?  What do you see in the audit log when the rule runs?

Until we see that information...Two possible improvements to your rule could be:

  • only trigger the rule when your custom field is updated
  • modify your JQL to exclude the trigger issue's key; otherwise it could try to link to itself

Kind regards,

Hi Bill ,

Thank you for your prompt response. I get the below error after running the rule




Yes, that error matches what I noted earlier.  Please add this to your branch JQL to exclude the trigger issue:

AND key != {{triggerIssue.key}}

Hi Bill,

Here is the JQL query and it does not work. Do we need to include Document Number there ?

Project = PSTS AND Issuetype in ("Case Lead Task", "Technical Writing Task") AND "Document number" ~ {{issue.fields.Documentnumber}} AND key != {{triggerIssue.key}}



Sorry I missed this earlier, as your JQL is incorrect: it is comparing issues to themselves...Within a branch {{issue}} refers to the branching issue and not the trigger issue.  Please try this for your JQL:

Project = PSTS AND issueType IN ("Case Lead Task", "Technical Writing Task") AND "Document number" ~ {{triggerIssue.Document number}} AND key != {{triggerIssue.key}}

And if that not work, please use this how-to article to find the custom field ID for "Document number" and substitute that instead of the field name:

Hi Bill,


Thank you so much! it is very much appreciated.

It worked.
