 - Объединение нескольких прайс-листов в один файл
 - Поиск пар артикул-количество в любой сторонней таблице и экспорт в таблицу заказов
 - Подбор монтажных гильз для фитингов RAUTITAN
- Подбор ремонтных муфт по количеству трубы
 - Экспорт таблицы заказов в девятиграфку по ГОСТ

 *Для работы функций "Экспорт", "Актуализация" и "Объединение" требуется указать путь к файлу пустого прайс-листа РЕХАУ*

 ## Реализованные формулы для работы с артикулами
- ```=РЕХАУ()``` - поиск артикула РЕХАУ по произвольному запросу в сервисе [RhSolutions-Api](https://gitea.cebotari.ru/chebser/RhSolutions-Api) 
+- ```=RHSOLUTIONS()``` и ```=РЕХАУ()``` - поиск в удаленной базе данных
 - ```=РЕХАУАРТИКУЛ()``` - экстракция артикула РЕХАУ из любой строки по регулярному выражению
 - ```=РЕХАУИМЯ()``` - поиск названия артикула по номеру
 - ```=РЕХАУЦЕНА()``` - поиск цены в евро по номеру артикула
