Is it possible to add the Sub-Task Original estimate in Parent Task?

[Mohammed Anwar Shaikh]

Hi,
Is it possible to add the Original Estimate of Sub Task in the Parent Task?

I have multiple sub tasks for each parent task and would like to add the sub-tasks original estimate to be get added in the Parent task.

I tried Automation, but didn't got any success. 

Any idea, is it possible in Jira Work Management?

Regards,

You'll need some code for updating the fix version on to the sub-tasks - a listener would be best as it can detect any change and cascade the result.

Epic Link is not a field that will work on sub-tasks.  You'll need to copy it to another field.
