Automatically Link issues to other issues with automation

[Seww]

Hello! I have two Automations that under certain conditions create two tasks in different projects, let's call them B and C. Tasks B and C are linked to the parent task A, how can i use Automation to configure the linking of tasks B and C to each other?

Hi @Seww welcome to Atlassian Community.

In your case, I see you're trying to do a retroactive action - Automations are often used for pos actions (when something happens, do this).

We can still use Automations for historical changes, by using the new Trigger When: Scheduled - which allow you to use a JQL as trigger.

I thought a bit about your case, even tried implementing a mock of it:  

So the way I would do is, loop through all issues under your epic by querying parent=epic_issue_key and open a JQL Branch, for again looping through all issues under that certain epic.

This essentially will create a nested loop, where every children of your epic will link to every other children of your epic.

Now I suppose you wouldn't want to do that, but that's what your description entails. I would start with this logic and tune it further to your needs.

Hope it helps!
