Sum of custom field from all the linked child stories to a field in parent story

Swapnil Tiwari_e203pt

Consider below scenario -

I have field in story - "Field_1"

I have created link - Outward Description > is parent of

Inward Description > is child of

 

Now,

I want to sum up the values from all the child stories to parent story.

(We can have a scripted field configured to carry the sum of the values. Let that field be Field_2)

 

Eg- 

I have a parent story AB-123

I have three child stories linked to AB-123, let that be AB-124, AB-125, and AB126.

 

I want to sum the value of Field_1 of all the child stories to Field_2 of the parent story.

Can anyone help me out.

You say you have a "scripted field" for field_2. 

That means you have a scripting add-on and you should be able to create another scripted field for "read all subtasks for the data of field 2 and place it in field 1 on the parent".  It should be able to do simply issue.getSubtasks() to get the list.
