Copy Assignee from Sub-task to parent custom field

[Ammara_Samar]

Hello, 

I want to fetch value from "Assignee" field of linked issue type Sub-task. And assign it to one of the custom field of parent.

Appreciate your help.

Hi @Ammara_Samar,

If you are using JSU plugin you can achieve this without any scripting. 

it does provide post-function called "Copy Value From Other Field (JSU)"

>> Copies the value of one field to another, either within the same issue or between related issues (as issue link, Parent/Sub-Task, Epic/issues in Epic or found by JQL).

BR,

Leo

Thanks @Leo  for your reply,

Unfortunately, we don't have JSU Plugin and its paid add-on.

Hi @Ammara_Samar ,

is it possible to use some add-on to achieve this? I would recommend you to use Adaptavist ScriptRunner and create custom groovy script. When this copy action should happen? Like during some transition?

Thanks '@Hana Kučerová  for your reply,

Yes I want to apply it on certain transition in workflow.

Dear, any alternate option than to go for groovy script?

You are going to need one of the scripting or automation plugins. 

If you do go for Scriptrunner, https://library.adaptavist.com/entity/copy-field-value-from-parent-issue-to-sub-task-upon-creation might be a good starting point.  It's actually upside-down, but should give you enough of the code you need to invert it.
