Is there a type conversion function?

Question

1C

It is necessary to convert a variable from a string or number to "Additional value".
Does such a function exist in 1C?

Answer 1

НоваяСтрокаЗначений.Значение= Справочники.ЗначенияСвойствОбъектов.НайтиПоНаименованию("НазваниеСвойстваДопРеквизита", Истина);

Answer 2

The question was posed incorrectly.
"Additional value" is not a 1C mechanism. This is a reference book that the developers came up with in some configuration. In other configurations (if they do not inherit this one), it may not be. Therefore, only by examining the library of available functions of your configuration will you know the answer to the question "Does such a function exist?"
Most likely there is some common module of the same name, where there is a complete set of tools for working with this directory. If the general module is not found, then you can search in the manager module of this directory.

Answer 3

no, just write. Additional value is a reference and you need to describe its creation.
