Can we sum up the story points of all child issues and update the Epic parent's story point??
Asked by Mohini Chandwani:

Consider an Epic parent, have 3 child issue of Bug,Improvement and New feature and we want the rule to sum up all the story point of these 3 child issues to Parent's story point.

The problem of tasks and subtasks being limited to a single level (you cannot create several nested subtasks). As a result, it is possible, for a tree structure of this type, to use the principle of Parentlink/Childlink

I've seen all of these answers (about "sum" pbl), which work great for task and subtask cases. On the other hand, it is impossible to run a procedure correctly with the ParentLink / childlink. For these cases, we fall into the same process. Do you have a solution for this type of case?

Example  
child sheet = 10 and 20.  
the first step is ok and the parentlink file is at 30.  
if child 1 is modified (10-\>15), the parent changes to 45 (instead of 35).

Any idea ?

Thanks all.

There's this documentation that might help you implementing this without the need to use Lookup action (which is only available for Cloud instances):

Can you please take a look and see if it matches what you need?

In your link, this is with "{{issue.subtasks.Story Points.sum}}" ... and so, with only "subtasks". For me, "subtasks" is to list all issues in case of "Task / subtask". So, in this case we use "Parent" in branch to get task and "subtasks" to get all issues

In my case, we don't use task/subtask. Issues are linked with "parent link". Have you keywords for issues in context "Parent/Child" ? to get parent, we use "issue IN parentIssuesOf( {{issue.key}} )" ... but how to get all (and sum) about child's issues ? something like "childs" ?

body: The link you shared in that I am unable to add "lookup" issue component, its not available for me.

There are two approaches I have figured out :

1.Find out all the child issues of Epic parent and sum up the "Story Points" of child issue and add up to Parent.

Problem : unable to find out the child issues using automation rule, how to get all those?

2.I tried using the {{triggerIssue.Story Points}} + {{issue.Story Points}} option but that continues to add like :

Story issue A = 12

Bug issue B = 10

Parent issue = 22 (first time it is correct)

This is fine so far but

Story issue A : 12 -\> 15 (updated)

Parent Issue = 37 (not 25 like it should)

How to remove the Old Story Point and add new Story Point using smart values with rule.

Have read the articles, suggested to use join("+") that also does not work.

What can be the correct approach, please suggest.

Thank you for the immediate and valuable response.

Looking forward for more response.

author: testJira seb
body: Hi Victor ; not the good one because you use "task/subtask" and I use parent/child.

I have to wait for it ;-)
