function copy_from_fields_to_propertys_values($IBLOCK_ID){
    if ( CModule::IncludeModule ( "iblock" ) ){
        $arOrder = array(
            "sort" => "ASC",

        while ( $arElement = $db_elemens->GetNextElement() ) {
          
            $el = new CIBlockElement;
            $filds = $arElement->GetFields();

Answer 1

If you want to save in a property then PROPERTY_ SUBSCRIBE

Answer 2

This property is not an infblock, but a trade catalog

Answer 3

method , below there is an example with SUBSCRIBE (only this is a static method):
D - by default, from the module settings Y
- yes
N - no
UPD
still in the source code it is written that the method is deprecated, use

\Bitrix\Catalog\Model\Product::update($id, ['SUBSCRIBE' => 'Y']);

UPDUPD
here is an example with CAN_BUY_ZERO, replace it with SUBSCRIBE - it will drive for once
