When I update Due Date in Issue A, I want to transition Issue B (in same Epic) to 'Done'

Hi all

I can't get my automation to work.  I have a number of epics in my project, with each epic having the same 11 Tasks in them.  All 11 have the following convention "NAME - Task A" "NAME - Task B", etc.   The 'name' is different for each epic.

I want Task A to update to 'Done' when a due date is entered for Task B


Anyone any tips on what I'm doing wrong?  The issue I'm getting is that 'No related issues could be found'

Appreciate any help here!

Hi @Liam Green 

Is this Classic or NextGen?  And, are you saying the Branch is finding no sibling stories for the Epic?

Maybe add a log action prior to the branch to see the issue type of the triggering issue, and its parent, to confirm what is happening.

Best regards,


Hi @Bill Sheboy 

It's classic, and yes - the branch is finding no siblings.  The trigger issue is a Task, all the issues in the epic are tasks.  I wanted to use JQL to search the epic for any Tasks with a summary ~ "- Scheduled" (as there should only be one in each) but "epic link" = {{triggerissue.epiclink}} didn't work

Gotcha.  Please try {{issue.epic link}}

Perfect Bill, thank you so much!
