Notes:
- When the process reaches the automated task, the Qorg settings of the Workflow Platform are referred.
    - To explicitly and automatically determine the person in charge.
    - The Process Status "Offered" is avoided.

Notes-ja:
- 案件が自動処理工程に到達した際、ワークフロー基盤の Qorg 設定を参照し、一人を抽出します。
    - 明示的・自動的に担当者を決めたい場合などに利用されます。
    - プロセス状態「引き受け待ち」を回避できます。
