Hi @Priya you can create an automation rule for this. 

Example Automation Rule:

Trigger: Issue Created

Condition: Issue Type = Subtask

Branch: Parent Issue (Epic)

Action: Edit Issue (Copy values from Epic to subtask using smart values like {{issue.epic.field}})

Summary of Smart Values:

Copy Summary: {{issue.epic.summary}}

Copy a custom field: {{issue.epic.customfield_10000}} (replace with the actual field ID)

Copy Labels: {{issue.epic.labels}}

Copy Priority: {{issue.epic.priority.name}}
