Проблема обновления производственного заказа SAP b1 с несколькими партиями ⇐ C#

[Anonymous]

У нас есть разработка специального надстройки, заменяющая окно распределения партий SAP b1 на нашу разработку надстройки для окна распределения пользовательских партий (control+Tab).
При выделении нескольких партий одному и тому же элементу при нажатии кнопки обновления формы производственного заказа SAP B1 после выделения партии после всплывающего окна с ошибкой в журнале системных сообщений.
пример — при вводе данных из входа в систему менеджера, даже если все подключенные клиенты, связанные с логином(ами) менеджера, отключены, еще ниже появляется ошибка

Данные изменились другим пользователем или другой операцией; чтобы продолжить, снова откройте окно «Пользовательские значения» (CSHS) (ODBC -2039) [Сообщение 131-183]

Посоветуйте мне, что нужно исправить.
