Hi @PRAMOD KUMAR REDDY KASIREDDY ,

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.

Or if you are using Jira Cloud then you can use Automation in  Jira to copy the parent field in Subtask.

Thanks,

Mayur
