I'm just confused about these "process product additional fields" and "product additional fields". As far as I understand, if you need to pass the value of the product, but it is directly in the process (for example, an order), then this is an additional field of the process product?
The bottom line is that when unloading an order from Box, the product field must be transmitted

here should be the value of the additional field of the product "Name for 1C"
