How to register a product article in Bitrix?

Question

1C-Bitrix

I apologize in advance for the stupid question. But you have to learn. When adding a product to Bitrix 1c, where does the article come from, do I need to invent it or is it already registered somewhere? I really need your help, please!

Answer 1

When loading from 1C, the article is added to the product property

Answer 2

Here is the answer to the question what is the name of the Bitrix Article property and that by default it is not in the info block Product Article in Bitrix. Where is it located in the infoblock and what is the name of its code?
