Как сохранить 2 и более таблицы C# access?

Такая проблема. Не получается сохранить 2 таблицы.

Есть 2 таблицы : договоры и детали договоров. Форма договора заполняет сам договор и ниже таблица с деталями и навигатором через который я добавляю детали договора на другой форме.Сохранение 2ух таблиц сразу И так же имеется кнопка сохранить... однако она сохраняет только таблицу договоров но не детали Код привязан к кнопке сохранить

private void productsReceiptBindingNavigatorSaveItem_Click(object sender, EventArgs e)
        {
            this.Validate();
            this.productsReceiptBindingSource.EndEdit();
            this.productsReceiptDetailsBindingSource.EndEdit();
            this.tableAdapterManager.UpdateAll(this.comfortHouseDataSet);
        }`

Код привязан к добавлению деталей накладной

private void DetailsAddNewItem_Click(object sender, EventArgs e)
    {
        DataRowView newDetail = (DataRowView)this.productsReceiptDetailsBindingSource.AddNew();

        frmPructsReceiptDetails detailForm = new frmPructsReceiptDetails();

        using (detailForm)
        {
            detailForm.EditDetails(this.productsReceiptDetailsBindingSource, this.productsBindingSource);
        }
    }

А этот на форме с деталями
