Здравствуйте, busik, Вы писали:

B>Как построить выражения в таблице отчета так, чтобы в ячейках таблицы выводились значения из разных таблиц.
B>например:
B>есть таблица с полями
B>материал;код
B>и вторая таблица
B>код;описание

B>а в отчете надо вывести
B>материал описание

B>причем описание чтоб соответствовало материалу по связующему полю "код"

B>в первой ячейке будет
B>Fields!Code.Value

B>а вот как следует написать выражение во второй ячейке?

B>Зарание спасибо!
