要約

When attempting to update existing subtask tickets using a CSV import in Jira, users may encounter the following error:

Issue can't be created as issue type is sub-task but parent issue key or id is not specified.

原因

This error arises when the issue type is mapped during updating existing subtasks using CSV import.

ソリューション

To successfully update existing subtasks without encountering this error, ensure that the issue type is not mapped during the import process. You only need to provide three fields:

• 課題キー
• 要約
• The field you wish to update

The same applies when updating any issue regardless of its issue type.
