Requality

У документа есть три фрагмент. Два из них принадлежат требованию 001. Один фрагмент - требованию 002.

1. Копируем и вставляем рядом требование 001.
Видим, что создалось требование 003, имеющее те же фрагменты, что и 001.

2. Открываем документ в редакторе Document Editor. Это важно! Если он уже был открыт, переоткрываем заново, иначе может не воспроизвестись.

3. Делаем undo.

Появляется сообщение об ошибке: "Abnormal Workbench Condition".
