Actually a subject))
how to delete all user properties of an infoblock element without knowing their ID and External code, input data is only ELEMENT_ID and IBLOCK_ID?

so delete one by one knowing its external code or id

CIBlockElement::SetPropertyValuesEx($arData['PRODUCT_ID'], $arData['IBLOCK_ID'], array($arData['EXT_ID'] => Array ("VALUE" => array("del" => "Y"))));

but there are no input data for the property itself, i.e. we don’t know if the element has properties or not, we just need to delete or clear everything that it may or may not have.
