How do I get a custom field from parent task to auto populate on subtask?

[Jason Chayer]

I have Jira Software 9.0, but do not have Automation. My question is how do I get a custom field from the parent task to auto populate on a subtask that is created from that parent? Again, not using Automation.

Hi @Jason Chayer ,

If you are looking to copy the field value when a sub-task is created, you can add them as a post-function on create issue transition. 

JWME app offers a post-function "Copy field value from parent issue (JMWE app)".

Here is a script runner code - https://library.adaptavist.com/entity/copy-field-value-from-parent-issue-to-sub-task-upon-creation

Add this as the first post function on the Create step of a workflow

So, Jira does not do this natively, I will need an app?

You are right
